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. READ MORE

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.

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 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, READ MORE
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

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 READ MORE
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.

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.

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.

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

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.

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 READ MORE
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.

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.

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 READ MORE
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.

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.

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.

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.

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.

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.
