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.

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 READ MORE
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.

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.

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 READ MORE
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 READ MORE
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.

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 READ MORE
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.

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 READ MORE

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.

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.
