Iridotomy Specialist

What is an iridotomy?

Iridotomy is the standard treatment for closed-angle glaucoma. This laser procedure can also prevent further damage to the optic nerve that results from the condition. 

The goal of iridotomy is to increase the efficiency of fluid drainage from the eye to help you maintain normal pressure. 

Why do I need an iridotomy?

Closed-angle glaucoma describes a condition where the drainage meshwork is blocked or closed in certain areas. The angle is the space between your cornea (the clear part of your eye) and the iris (the colored area) that contains trabecular meshwork that drains fluid.

When something blocks the meshwork, it causes fluid to build up in your eye and put pressure on your optic nerve. Without treatment, this type of glaucoma can lead to irreversible blindness. 

Dr. Prince may recommend iridotomy if you have persistently high eye pressure or glaucoma. If you have normal eye pressure but have a closed angle, you may benefit from iridotomy as a preventive treatment to reduce your risk for glaucoma. 

What happens during iridotomy?

During an iridotomy, Dr. Prince uses a laser to create a hole in the outer edge of your iris and widen the angle. This exposes the trabecular meshwork to increase the drainage of excess fluids. 

You will receive eyedrops to make your pupil small and anesthetic drops to numb the surface of your eye. Dr. Prince then places a special lens on your eye to guide the laser. 

Typically, iridotomy takes up to 10 minutes and may cause mild discomfort. You can expect to have some vision blurriness and increased sensitivity to light. Dr. Prince and his staff can prescribe medicated eye drops to control inflammation after your iridotomy. 

How long do the results of an iridotomy last?

Iridotomy is effective in many people with closed-angle glaucoma. Depending on your specific situation, you may need additional treatment and medications even after iridotomy. 

The lasting effects of an iridotomy depend on many factors. Often, normal age-related changes and cataracts can close the angle again. Dr. Prince works closely with you to manage your condition in the long term and can recommend other options for preventing optic nerve damage and other complications of glaucoma.
