  • Are lenses better than glasses?

    If by lenses you mean contact lenses and not intraocular lenses, which require surgery, then I would say they are somewhat equivalent. Contact lenses require a trained ophthalmologist or optometrist to examine the eye to be assured that no disease process exists within the eye or on the corneal surface (the tissue upon which the contact rests). He or she will then take measurements of the curvature of each eye and determine the shape of each eye and determines the substance that the contact lens should be made from. This is a firm plexiglass material for a hard contact lens or an acrylic gel that is the flexible soft lens. If no disease exists then a training time should be set aside to allow you to learn How to put these lenses onto the corneal surface and, how to take them out. Though soft lenses are more comfortable to most than hard lenses, they can be placed back to front and not provide good enough vision. Intraocular lenses are now routinely placed after cataract surgery. They take the place of the natural lens that was within your eye and can be used to create good vision at all ranges, often without the need for glasses. Intraocular lenses must be surgically implanted with in the eye and are a higher level of risk. These surgeries are only performed by a qualified ophthalmologist who has gone through four years of medical school before entering the three-year Ophthalmology training program. Some eye specialists specialize in contact lens related practices. They are either an optometrist or an ophthalmologist, or an office that has both. Roger Ohanesian, MD READ MORE

  • How do you get rid of conjunctivitis?

    There are any causes of what you are referring to as “conjunctivitis. “ Depe Ding upon the etiology (cause) of the redness and scratchy irritated dry feeling of your eyes, there are different treatments. Your conjunctivitis can be due to dry eyes from a number of different reasons of bacterial or viral or fungal or even parasitic or allergic diseases or even a combination of more than one. Rather than spend a lot of money and wasted time treating with the WRONG medication, go to a qualified, experienced general Ophthalmologist or one who specializes in “Anterior Segment Diseases of the Eye to learn what you have and be treated properly the first time. If you MUST try a home remedy first, take a clean wash cloth, dip it into warm to hot water (don’t scald yourself) then wring our the drips and place it on your closed eye(s)——-for thirty seconds. Remove it, place it in the warm-hot water again, wring it out and place it on your eye or eyes again. Continue that for five minutes and repeat this sequence four times a day: breakfast, lunch, supper, bedtime for one week. If it remains then get yourself to an ophthalmologist. Roger Ohanesian, MD READ MORE

  • When should I be concerned about eye pain?

    Pain is an important feature to the human body. It calls attentivvon to something that is important. The more severe the pain, the more it should be attended to by an ophthalmologist. Some who have pain also experience light sensitivity If the pain is from the feeling of a foreign body in the eye, again, see an ophthalmologist in haste as it could become infected and cause permanent damage. RogerOhanesian MD READ MORE

  • What should your eye pressure be?

    Intraocular tension, often spoken of as intraocular pressure, should range between 11 and 21 by Goldman applanation measurement. If higher than 21, ocular hypertension can be responsible which ultimately results in Glaucoma and loss of vision. Roger Ohanesian MD READ MORE

  • Does double vision go away on its own?

    Double vision is the result of eyes not being aligned on a target. It can indicate a more serious neurological disorder and should be evaluated by an ophthalmologist, particularly, a neuro ophthalmologist. Not infrequently, the patient has had an Esotropia where one eye turns in and is not aligned with the other eye, commonly known as “crossed eyes” or if turned out, “wall eyes “ known medically as exotropia. If no previous history of esotropia or exotropia, the ophthalmologist will examine the Cornea, lens or retina to determine if an opacity or loss of clarity of the Cornea or lens structures within the front part of the eye might be causing the unequal and therefore double vision or if the retina in the back portion of the eye shows a defect that might be causing the doubling of vision. Other reasons that might be causing this have to do with the nerves and muscles of the eye which require the services of a neuro ophthalmologist to determine why the eye muscle system which requires precise alignment Is not functioning. Alcohol in too much quantity can cause a temporary malalignment that passes after sobriety reoccurs Roger Ohanesian MD. READ MORE

  • When should I be worried about eye twitching?

    There are many causes to eye twitching and the most common have to do with neurological triggering of the superior levator muscle. Additionally, it can be caused by a foreign body embedded in the Cornea or lid or in the tear film. Additionally, a chalazion, commonly known as a “Sty” can be the cause of twitching of the lid. Treatment by removal of the foreign body or Chalazion of present can be effective. If neurological, Botox injection has been successful to break the cycle of twitching. This product by ALLERGAN Pharmaceutical has been used by ophthalmic plastic surgeons to decrease or eliminate Superior Levator Spasm as well. In this neurologic condition, the eyelid clenches closed tightly and cannot be opened without manipulation, or Botox. The Neurological component can be brought about during stressful episodes in the life of some persons. Roger Ohanesian, MD READ MORE

  • Can dehydration cause blurred vision?

    While I have not seen any literature about this topic, I do not believe dehydration as many of us experience it, can cause blurring of vision. In its extreme case, it may certainly cause blurred vision as well as blood clotting in blood vessels which have reduced serum and colliding red blood cells. Roger Ohanesian MD READ MORE

  • Can astigmatism be cured?

    Yes. See an ophthalmologist who performs LASIK or who is a corneal surgeon. Roger Ohanesian MD READ MORE

  • What are the treatment options for conjunctivitis?

    It depends upon the etiology of your conjunctivitis. If caused by exposure to an air borne allergen, or a virus or bacteria, the treatment is different. I will frequently advise warm compresses prior to topical medication if no signs of a viral nor bacteria is present. Often, dryness of the eye due to a reduction of tears is responsible. This disorder is also benefitted by warm compresses as well as the use of artificial tears taken during times of burning irritation of the eyes. Roger Ohanesian, MD READ MORE

  • Why is there blood in my eye?

    You could have a hemorrhage from a ruptured capillary vessel caused by rubbing the eye too vigorously causing the fragile vessel to rupture sand bleed until the pressure of that blood beneath the thin clear fibrous tissue (Conjunctiva) causes the blood to stop flowing. It generally goes away within a week, becoming darker red each day, and is innocuous. You can hasten its disappearance by applying a warm compress for several minutes four times a day. Use a clean wash cloth dipped into warm water, squeeze out drips and apply for 30 seconds. Then dip into the warm to hot water again, squeeze out drips again and reapply for another 30 seconds. Keep that going for five minutes and repeat again 4 times a day. Roger Ohanesian MD READ MORE

  • Why is my eye swollen?

    Could be a Chalazion, in common terms, a “Sty”. Depending upon the size and whether it becomes reduced by treatment with Warm Compresses(washcloth rolled up like a Shushi and placed in warm to hot water, squeeze to wring out drips and place on both eyes for 30 seconds, then place in warm/hot water again, wring out drips and place on closed eyes for another 3 seconds. Keep up that routine for five minutes and do that 4 times a day for one week. If the swelling persists you may need to see an ophthalmologist as it might be infected and need antibiotic eye drops to resolve. If it persists, a surgical procedure may become necessary to drain the pus that has accumulated in this infected Meibobian oil gland. But the warm compress method resolves the majority of Chalazia READ MORE

  • What is a vitrectomy?

    Your doctor wishes to perform a vitrectomy to remove all the vitreous that has been mixed with blood and has reduced your vision considerably. He has a twofold reason for doing this: First is to remove all the vitreous that is mixed with blood and reverting you from seeing well with this eye. A second reason is that blood mixed with Vitreous becomes sticky, and can be the cause of a retinal hole or tear which could lead to a retina detachment which is a very serious disorder and can cause permanent blindness. Roger READ MORE

  • Do I have pink eye?

    Could be many things but mostly it sounds like an Allergic Conjunctivitis. The tip off is the itchy pink eyes. We often add the term “burning.” This triad of Itchy, Burny, PinkEyes is common in Spring and Fall and should be considered with every case presentation with these symptoms. Another common diagnosis may be dry eye. There are others including viral and bacterial conjunctivitis. Treatment is dependent upon the findings of the ophthalmologist. Roger Ohanesian MD READ MORE

  • What is this bump on my eyelid?

    It sounds like a Chalazion which is a blockage of a tear gland that then becomes infected causing a greater degree of swelling. Following this, it becomes liquified and can then become solidified. Go to an Ophthalmologist for an expert opinion and see whether it requires an incision and drainage or a biopsy. This a very visible part of your eyelid and abnormalities should be examined earlier than waiting 5 months. READ MORE

  • Is it normal for kids to see floaters?

    No. Floaters are usually caused by the gradual deterioration of Vitreous, a gelatinous material within the eye that fills most of the globe. It undergoes a gel to liquid transformation in the fourth to fifth decade of life, but can occur earlier if the eye suffers trauma. Then the Vitreous liquifies and leaves behind Vitreous condensations known as floaters. If the trauma, an elbow or finger thrust into the eye, or even a hard fall may cause this to happen. More of concern is that these floaters might represent a tear to the retina with blood cells or clots emanating from the portion of torn retinal tissue. Any and all of these findings need to be evaluated by a skilled retina specialist or competent ophthalmologist. Early diagnosis and treatment are essential for recovery if these more serious diseases are present. Do not waste time, call an ophthalmologist immediately. Roger Ohanesian, MD READ MORE

  • Is it possible to remove an eye freckle?

    This could represent a thinning of the sclera, the white fibrotic part of the eye. Alternatively, it could be a lesion that arose from some pigmented tissue and would need to be examined by biopsy under the microscope. In either case, you should be seen by an ophthalmologist for further evaluation and recommendations. Preferably one who specializes in plastic and reconstructive surgery. Roger Ohanesian, MD READ MORE

  • Can kids have astigmatism?

    Yes. Astigmatism is common. Though usually of a low amount and not bothersome, it can be higher and cause significant blurring. It is best treated early to prevent disturbances in acuity that can cause life long uncorrectable blurring in vision. Untreated high astigmatism is one of the most frequent causes of the development of Amblyopia or “Lazy Eye” that happens in children in the first six years of life. If recognized and treated, it is usually resolved. Early diagnosis and treatment is the best treatment to prevent this problem and allow for restoration of sight, many times with just a pair of glasses. Roger Ohanesian, MD READ MORE

  • What is this white bump on my son's eyelid?

    The list of “could be” diagnoses is long. Starting with superficial folliculitis or Meibobian cysts to more dangerous elements such as Basal cell or sebaceous cell cancers. Best opinion is to have child be seen by a qualified ophthalmologist or dermatologist. A biopsy might be needed, or not. Roger Ohanesian, MD READ MORE

  • Why am I seeing flashes in my eye?

    Flashes of light indicate a retinal irritation as a possible traction upon your retina. This should definitely be examined by a retina specialist who would perform a thorough examination of your retina. You might have a tear to the Retina which would evolve into a fully detached which can be treated if early much easier than later. Roger Ohanesian, MD READ MORE

  • Will I be given antibiotics during my retina surgery?

    You will be given topical and perhaps even systemic antibiotics for your Retinal surgery unless it involves Laser only and no cutting of tissue. Roger Ohanesian MD READ MORE

  • Can optometrists treat glaucoma, or should I go to an ophthalmologist?

    Glaucoma is a complex disorder which can cause blindness if not treated appropriately. As an ophthalmologist with 45 years of experience, I have seen too many patients under treated by well meaning optometrists who have diagnosed the disease, but in whom the disease has continued to progress. I now will see all patients, but if glaucoma is suspected or diagnosed, I will refer them to an associate within our practice whose practice is devoted to glaucoma. He keeps abreast of all the nuances of modern treatment for glaucoma. If a patient has a cataract and has glaucoma, I would refer that patient to the doctor who can treat both diseases simultaneously by surgery. While I will use an Istent to reduce or eliminate eyedrops, if there is visual field loss or severe cupping, I will refer the patient for one of the many newer surgeries for the disease of glaucoma. Roger Ohanesian, MD READ MORE

  • Can crossed eyes be corrected?

    Yes. Crossed eyes should be corrected as soon as possible. This is usually done by a pediatric ophthalmologist. Surgery is performed upon the eye muscles to properly align the gaze. Patching may be required to strengthen one of the eyes that has been repressed. Patching and muscle surgery and very successful in correction of this disorder. Roger Ohanesian, MD READ MORE

  • I have a bug bite in my eye. Will it settle on its own?

    I have heard many persons state that it was a bug that “bit” them in the eye. They did not see the big do that but felt something in the eye…a foreign body sensation. When examined with a slit lamp that can magnify things up to 40 times, I have never in nearly fifty years of practice, ever seen a bug bite. It would be unlikely as the eye tissues have many nerves and a bug would cause a rapid blink response causing the bug to fly away. More likely, this was a misdirected eyelash striking the cornea and causing a foreign body sensation or a chalazion (sty) developing in one of the oil secreting glands in undersurface of the lower eyelid. Treatment by using a warm compress placed upon the closed eye has worked very well if used twice to four times a day. If symptoms persist or if there appears to be thickened, pus-like tears, then seek the help of an ophthalmologist as an antibiotic may need to be prescribed. Roger Ohanesian, MD READ MORE

  • My eyes are really dry. What should I do?

    Warm compresses and Omega-3 capsules, also known as fish oil. Sometimes the Meibobian glands (top layer of the tear film) that produces the oil gets clogged if a person has Omega-6, which is a thicker oil and is prone to clogging the gland. Warm compresses allow the thickened oil to liquify and return to covering the water layer to prevent it from evaporating. Beneath the water layer is the mucous layer that causes the tear layers to adhere to the cornea. Eating salmon frequently can substitute for Omega-3, but is often more expensive. Roger Ohanesian, MD READ MORE

  • When is a vitrectomy used?

    Consider the vitreous to be similar to the albumin of an egg. If you crack a fresh egg, there is a membrane around the albumin and another around the yolk. If you crack a three week old egg, the albumen has degenerated and is now watery with white spots,condensations of protein in it. This is what happens to the vitreous in the eye. The amount that is still gelatinous is attached to the retina and can form traction as the eye moves up/down, right/left throughout the day. When this traction is in the periphery, it can pull firmly on the retina and cause a tear to the retina which might need and cause considerable blurring. Even worse is that the tear to the retina might allow the now watery vitreous to enter this tear and go behind the retina creating a Retinal detachment. If the traction from the shrinking retina is located in the center of the retina (the Macula) then it will cause serious damage to the center of vision from which recovery is limited. All of these conditions or even the distinct possibilities of traction upon these tissues may be the reasons to perform a vitrectomy and replace the vitreous with saline, a salt water substitute for the vitreous. Because this surgery is very delicate, it is only recommended in cases where there is the danger of further vitreous degeneration to result in one of these conditions or if particles of the protein concentrations (floaters) obscure the vision and are blurring the vision.

  • How is strabismus treated?

    Treatment for Strabismus is determined by the amount of eye turn. If minimal glasses with prisms are tried to bring the images seen from each eye together to coincide. If a greater amount is found, surgery on any of the six muscles of either eye , sometimes both, are operated upon to allow the child to see the same object with each eye in the same central part of the retina. READ MORE

  • Why do I have eye watering after a cataract surgery?

    If it has not improved after several weeks, you may have an irritation from the entry incision to the eye. This tissue usually heals within a few weeks but if not it may require treatment by your surgeon. He is the one to see regarding this disturbance. READ MORE

  • Can being in the sun without UV protection harm my eyes?

    The Ultraviolet rays of light from the sun are believed to be one of the risk factors toward Macular Degeneration and cataracts. Wearing sunglasses which filter out these rays reduces the incidence of these disorders. READ MORE

  • Can sunglasses spoil kids eyesight?

    Let him wear the sunglasses. They reduce his risk factor of damage from the harmful rays of the sun. READ MORE

  • My mother often complains of itchiness and stickiness in eyes. What is the remedy for this?

    She may have dry eye disease. It is very common and may be a result of a reduced oil secretion that comes from the eyelid. She might try using a washcloth rolled up like sushi dipped into warm water and with all the drips squeezed out, placed upon your eyes for 30 seconds. Then, return it to the warm water, squeeze out the drips, and keep it on for another 30 seconds. Keep doing that for five minutes and perform this 2-4 times a day. This may alleviate her discomfort. If it does not, she should see her ophthalmologist for further evaluation. READ MORE

  • I have slight pain in my right eyes and I am seeing spots frequently. What could be wrong?

    Time to see your ophthalmologist. You could have a Retinal disorder which causes these floating spots. The reasons for pain in the eye will also be evaluated during that visit. READ MORE

  • What is the prognosis of diabetic eye disease?

    Have your mom be seen by a retinal specialist. He will advise whether she has diabetic retinopathy and whether it should be treated by intravitrenous injection or laser to hopefully prevent loss of vision. Roger Ohanesian, MD READ MORE

  • I have a problem driving at night. Is there any way to fix it?

    You need to see an ophthalmologist. There are many different reasons for your symptoms, from cataracts to developing Myopia. Treatment is often possible by eyeglasses, but may require surgical removal of cataracts. Your ophthalmologist is probably able to give you treatment no matter what the condition might be. Roger Ohanesian, MD READ MORE

  • What are the precautions to be taken after laser surgery?

    Don’t rub your eyes. This can dislodge the flap of corneal tissue overlying the area of treatment. After a month, it is usually secure, but it's never wise to rub the eyes. Roger Ohanesian, MD READ MORE

  • second eye cataract removal

    No. But cataracts usually develop in each eye at about the same time, like gray hair. My advice to patients is to have surgery done when the cataracts are preventing you from doing something you need to do or want to do. I also advise that they not wait too long. I often travel to remote areas on humanitarian visits and see solid black cataracts. These are very difficult to remove and often will cause complications that are not found in cataract surgery on a less dense cataract. If one eye has a cataract and little appearance of it is seen in the other eye, then there is no urgency toward doing the second eye. As time goes on, it will become obvious and can be removed then. Roger Ohanesian, MD READ MORE

  • Why are my eyes watering after cataract surgery?

    Could be the depression where an incision was made on the cornea to enter the Anterior Chamber, a necessary step in cataract surgery. It usually heals and becomes less irritating and therefore has less watering within a month. If you have further watering, you should see your surgeon for confirmation. Roger Ohanesian, MD READ MORE

  • I accidentally slept in my contacts. Can just once cause permanent damage?

    Usually not, but repetitively can cause damage, sometimes permanent damage to the cornea and tear producing structures. Roger Ohanesian, MD READ MORE

  • How can I protect my eyes while working in front of the computer for close to 8 hours a day?

    Every 20 minutes look away from the computer at some distant object. Hold that gaze for 2 minutes then close your eyes for 2 minutes. This allows the muscles to relax and the eye to become well lubricated. Roger Ohanesian MD READ MORE

  • My mother's eyes always seem red. What could be the reason?

    Dry eyes happen to a large number of persons and your mom might be one of them. Have her stop rubbing her eyes and use artificial tears. If no improvement, see an ophthalmologist as it could represent something more serious - an infection from a virus, bacteria, parasite or allergy to something. Your eyes are important and should be treated well. That said, see an ophthalmologist for safety. Roger Ohanesian, MD READ MORE

  • Is it possible to salvage dried out contact lenses?

    Rehydrate them with the wetting solution. There is a possibility that they have cracked, but less likely if they have not been abused while dry. Roger Ohanesian, MD READ MORE

  • Why do I blink so often?

    You may have dry eye problems and need the added irrigation that occurs when you blink frequently. The Meibobian glands may be the culprit as they produce an oil that covers the top surface of the watery fluid of the tear and prevent it from evaporating. The bottom layer is the mucous which keeps the fluid onto the surface of the cornea. You may have MGD or Meibobian Gland Disease. The Meibobian glands produce this oil which is exuded onto your lid margins every time you blink. Aqueous fluid from your tear gland also is exuded as well as mucous which serves as the base element of the tear and sticks everything to the cornea. If you have a reduction of your Meibobian gland secretion, this makes the tear evaporate more rapidly making your eye feel dry and scratchy. Best advice I can give is for you to see an ophthalmologist. It would be ideal if you knew an eye dr who specializes in Dry Eye diseases. There are several doctors who do this. Roger Ohanesian MD READ MORE

  • My husband has a parasite eye infection. Is it contagious?

    This disease is probably Demodex Follicularum and is contagious. He probably has been advised to cleanse his eyelid and lashes with various medications that will kill the adult organism and the larva which live within the follicle of the lash. Consistent cleansing with these hypochlorites will kill off adults and larva over a two- to three-week time period. Family members are in jeopardy as the organism is able to pass from one person to another if close enough. If symptoms of itchy, burning, crusted lids occur in a family member who has been diagnosed with this parasite, safety would dictate that lid scrubs should also be considered if diagnosis is confirmed by an ophthalmologist. Roger Ohanesian, MD READ MORE

  • Why does my vision feel hazy in the morning?

    With symptoms like that, you might have a disease of the cornea (Fuchs Dystrophy), which causes the cornea to become swollen overnight when your eyelids are closed and the tears don’t evaporate. A test of the cornea is often done that demonstrates the loss of corneal cells that is present with this disease. Typically, hypertonic saline solution, basically salty tears, are placed into the eye at night and in the morning to reduce the swelling. It is generally successful and should be sufficient IF THAT IS THE DIAGNOSIS. We also worry about Glaucoma, which blurs the vision if the pressure goes up at night. Since there are different diseases that can be involved, it is essential to be seen by an ophthalmologist who may be able to make the diagnosis just during his examination. Roger Ohanesian, MD READ MORE

  • My mother is highly diabetic and is not able to see very clearly. Could it be the onset of glaucoma?

    If your mother has diabetes she has a higher risk of cataracts, glaucoma, and variability of vision due to refractive changes (eyeglasses) associated with sugar levels in her blood stream. That her vision may sometime blur and later clear makes me concerned that she may have vision threatening diabetic retinopathy. This is a very common yet serious complication of diabetes and must be treated quickly to prevent loss of vision. Mother should be seen by an ophthalmologist ASAP. She is in jeopardy of losing vision. She may require injections into the eye or laser to prevent further loss. If she has cataracts or glaucoma, her vision is at risk but treatment earlier is easier. If you are reluctant or have no time to take her to the ophthalmologist, you may find your life disrupted due to the need of caring for a parent who is permanently blind. Roger Ohanesian, MD READ MORE

  • My daughter is 3 years old and currently has swelling in her left eye. Is this a sty?

    I would definitely check with your pediatrician to confirm this to be a chalazion or hordeolum. These are blockages of glands that supply oils to the surface of the tear to prevent evaporation of the underneath water layer that is the lubricant and is over the mucous layer that makes the tear structure stick to the cornea. If these glands get infected, the oils they produce don’t flow and the result is often the chalazion or hordeolum. Treatment is often to roll up a wash cloth like a shushi and dip it into warm (not hot) water, squeeze out the drips and place on the closed eye for 30 seconds. Remove, replace in warm waters down, repeat for another 30 seconds. Continue that routine for 5 minutes and do that for five minutes, 4 times a day. Your doctor may ask you to take an antibiotic eye drop after each session. The lump should go away within a week. If not, check with an ophthalmologist. Roger Ohanesian, MD READ MORE

  • Why do some people have dry eyes?

    There are multiple reasons for Dry Eye and the treatment differs for many of them. Your Mother should be seen by an Ophthalmologist who specializes in the front surface of the eye. She/He could determine with testing whether her disorder is due to a condition that affects her whole body or just the eyes. She may need testing to determine if her tears are deficient of nutrients or if components are missing that allow for rapid evaporation. Dry Eye can be a hereditary disorder which might affect her children and grandchildren. A cure for Mom might make for an easier time for you and your kids. It’s worth taking her to her Ophthalmologist for evaluation and treatment. Roger Ohanesian MD Harvard Eye Associates READ MORE

  • Can a 3 year old child have glasses?

    Yes, children even as young as one year old may require glasses to prevent Amblyopia, also known as Lazy Eye, in one or both eyes. Depending upon the child, they may need to have lenses inserted into goggles to allow the glasses to stay in place. These glasses are often needed to prevent eyes becoming “crossed” or “wall eyed”. If you child is found to need glasses, confirm the diagnosis and treatment by having her visit a Pediatric Ophthalmologist if you have doubts about the first eye doctors opinion. But, don’t ignore the advice lest your child develops a lifelong reduction of vision. Roger Ohanesian MD Harvard Eye Associates READ MORE

  • My eyes feel very dry after LASIK. Why could this be?

    Of course you should return to your LASIK surgeon about your discomfort. It is not uncommon for dry eyes to occur after LASIK surgery as corneal nerves that innervate at the limball periphery enter the cornea at each side. These nerves commonly get cut during LASIK and need to regrow. Usually they do so after a month or so but sometimes it takes years and occasionally they don’t re innervate. It will be up to the LASIK or corneal surgeon to tell you what to do next. Artificial Tears might be best for you during the day and a gel or ointment at bedtime to get through the night. Roger Ohanesian MD READ MORE

  • Can diabetes cause reading difficulties?

    Your mother would do best by seeing an ophthalmologist as there are many reasons for her reduction of vision. If her “correction" for vision so that she saw without glasses was a cataract extraction, there is often a membrane that clouds over and requires a fast treatment by a YAG LASER that can clear her vision. If that is not the case and instead there is evidence of Diabetic Retinopathy with hemorrhages and exudates, she will certainly need injections into the eye and possibly a different type of (Argon) Laser. This is an urgent problem to resolve. If Diabetic changes exist within the retina, it is only a matter of time when your mother will lose significant amounts of vision. Diabetes is one of the most common causes for blindness throughout the world! If caught early, treatment can prevent vision loss. Have her see an Ophthalmologist as soon as possible. Roger Ohanesian MD READ MORE

  • Does not wearing glasses all the time increase eye power?

    That is a very good question, the answer to which requires the knowledge of whether without glasses, you have nearsightedness (able to see clearly at near but not see distant objects well) or farsightedness, able to see distance better, but not well for near. Then, there is astigmatism which means things are distorted at both distances and reading. After many years of practice, I have noticed that patients who have a small degree of any of these disorders will remain stable to a point, but the need for glasses increases the greater is the prescription power. My common refrain to patients is “If you see well enough, as tested by the eye chart, and your activities, and are comfortable without glasses, then go without them." It will not hurt you to go without glasses and wearing them might make you dependent upon them. Going without may be perfectly acceptable unless it prevents you from doing things you want or need to do. Remember though, just because you don’t want to wear glasses is not a good reason to not wear them. If you can see 20/25 or 20/30 without glasses, it might be acceptable to go without. For driving though, especially at night, you may be better to wear glasses as vision often drops when night falls. This is most true if you are driving. While doing this activity, you will want to have the best possible vision. Roger Ohanesian MD READ MORE

  • Is there an age restriction for a refractive surgery?

    There are very good reasons why refractive surgery is not done on children your daughter’s age. The principal one is that her eyes have not completed their growth cycle and may require significantly different lens power in later years. For her to go through this major refractive surgical procedure upon the cornea of each eye and then have further growth and subsequent blurring vision from eyes that are no longer focused would be disturbing to her, her parents and her surgeon. We typically prefer to not repeat the surgical procedure if it can be avoided as a distorted cornea can cause irregular astigmatism that is difficult to correct. Roger Ohanesian MD READ MORE

  • Why are my eyes blood red when I wake up?

    Let me know if you did not receive my reply. I sent it from Armenia where I was on a Mission Trip. Perhaps it did not get sent due to poor Internet service. Roger Ohanesian, MD READ MORE

  • Why are my eyes blood red when I wake up?

    Despite that every person with these symptoms feels they are alone in experiencing this malady, it is common and frequent among those who stare at a computer screen for long periods of time. Briefly, you have developed dry eyes from not blinking sufficiently when on the computer. When you concentrate on the screen close to your face, you blink less frequently. Because tears spread over the cornea and sclera, and these tears evaporate and cool the Cornea thereby reducing the oxygen need. When the corneal cells cry out for more oxygen, blood vessels in the adjacent tissue (conjunctiva) respond by enlarging and bring more oxygen from the tiny blood capillaries around the eye to the cornea. Though the eye is more comfortable, it becomes red and makes you uncomfortable. Treatment may be by: PREVENTION. READ MORE

  • Can diabetes cause reading difficulties?

    Given that your Mom is a long term Diabetic and 60 Years old, there are many things that come to mind to cause decreased abilities to read. The first is that despite having Refractive Surgery so she did not have to wear glasses she may need glasses for upclose due to her lens becoming more rigid and not providing enough magnification to allow comfortable reading. This is easily diagnosed and treated by testing reading glasses sold at most drugstores for less than ten dollars. Another possible diagnosis is of cataract formation that may have clouded her vision and caused her difficulty in reading. Diabetes may accelerate the development of cataracts and cause a central Posterior SubCapsular cataract which is especially bothersome when reading. Because this cataract frequently blurs the very center of the pupil it causes distortions and deminished acuity up close. Because when looking up close, the pupil constricts allowing only rays coming from the center to pass through the pupil and the center is the most clouded portion of this type of cataract. Another disorder found frequently in type 2 Diabetics is the presence of Diabetic Macula Edema. This blurring is due to the presence of fluid within the layers of the central retina causing the patient to have reduced central vision. A Fourth reason may be often presence of Diabetic Retinopathy which occurs in one third of Diabetics and can be vision threatening in one third of those with Diabetic Retinopathy. This would require intravitreal injection or Argon Green Laser to a significant portion of the retina. An examination must be done as soon as possible by a qualified Ophthalmologist or retinal specialist. If vision threatening Diabetic Retinopathy exists then treatment should take place ASAP.

  • What is the reason for double vision following an accident?

    First and foremost, he must be seen by a qualified ophthalmologist (MD). There are many aspects of the eye that need to be thoroughly examined because other parts of the eye may have been injured. After a bicycle accident 3 month ago (in late June or July) when the rider was most likely wearing a helmet and sunglasses,I suspect he hit the ground on the lower side of his face and his glasses were propelled up. This caused the nose bridge projections (those clear plastic devices on the inside of the frame) to slam up to the bony orbit and damage the "Trochlea." He may have noticed that pressing on the uppermost nasal portion of the orbital bone would cause pain on the injured side but no tenderness on the opposite eye upper nasal orbit. This Trochlea is a pulley that transfers the pulling action of the "Superior Internal Oblique" ocular muscle to make the eye turn down and in. If damaged or fractured, the pulley does not function with needed pin point accuracy. Because each eye is like a video camera and both eyes must coincide on the same place to not get a blurred image, the DAMAGED Trochlea causes the eyes to be out of alignment. After a dilated retinal exam by an MD ophthalmologist, the patient should be seen by an Ophthalmic plastic surgeon or ocular motility specialist for possible repair of the condition. His double vision may encompass both horizontal and vertical elements and may need to be treated with prism glasses even after surgical repair. He may find that, when looking at a light in the distance, one eye sees it above the other and maybe side by side too. Unfortunately, these double images (medical term: Diplopia) may last a long time and require prism glasses for correction. Good luck. Roger Ohanesian MD READ MORE

  • Can eyesight ever get better on its own?

    You have noticed a common source of anxiety about vision. In your teenage years, your tissues continue to grow, as they are supposed to do. This includes your eyeball which often gets bigger, and vision becomes more distorted, as you age. This is especially true among nearsighted persons whose retina becomes further and further back (posterior) as the eye swells to achieve its final shape. When this happens, the image upon the retina becomes out of focus and glasses are needed to place it once more put it into focus. You can think of the analogy of a projector perfectly displaying an image up READ MORE

  • Anything to watch out for when using glaucoma eye drops?

    You should review the package insert to see if you have known allergies with any of the ingredients of the medicine you have been advised to take. Lumigan, which you have been advised to take. Also, ask your GP or Internist if he has any concerns regarding this or that eyedrop. Then read the side effects of a given medication. For example Lumigan has an effect of occasionally causing increased pigment to adjacent skin and causing longer lash growth and darkening and growth of lashes. This might be bothersome to some users. Lastly, if you have not already done so, make a complete list of your medicines, how often they are taken and their route of administration (by mouth, inhaled, eyedrops etc. then keep in a safe easily found place.

  • My eye looks different because of my astigmatism. Anything I can do?

    If you mean "my eye sees differently" than the other eye. That is understandable. If the appearance is different, that would require a visit to an ophthalmologist. The distorted image that an eye with astigmatism produces is different than one with no astigmatism, but the appearance of the eye when looked at through a mirror or by another person, should be no different. If it is different, it should be examined by an ophthalmologist. Roger Ohanesian MD READ MORE

  • Why are my eyes sore after contacts?

    Lots of reasons for this symptom. May have to do with CL diameter, curvature or cleanliness. It may also be a result of a dry eye condition. Many persons do not take their soft contact lenses CLs out for many days. If that is you, start taking them out during hours of sleep. Lastly, use warm compresses on your eyes. leave on for 30 seconds then refresh compress in a bowl of warm water, squeeze then Back on the eyes for another 30 seconds. Continue for five minutes or ten applications. I have found this makes most patients far more comfortable. But, of the discomfort remains, see your CL specialist or ophthalmologists.
