Glaucoma affects an estimated three million Americans, but only half of those living with this eye disease know they have it. Lack of awareness surrounding the condition is problematic, as it can cause permanent blindness if it isn’t handled properly. Find out what eye doctors want every patient to know about this disease. 

Glaucoma FAQs

What Causes Glaucoma?

This disease occurs when the optic nerve is damaged, usually due to increased pressure in the eye. The fluid your eyes produce normally drains naturally, but if it does not—because the passages that allow fluid to drain become clogged or blocked—the buildup places pressure on the optic nerve.

Can It Be Prevented?

Eye doctors remain unsure of why the passages that normally drain fluid from the eye get clogged or blocked. Since the cause for this is unknown, doctors also aren’t sure how to prevent glaucoma. Additionally, some people may still contract the illness even if the pressure in their eyes is normal, possibly because of poor blood flow to the optic nerve.

Are Their Identifiable Risk Factors?

In general, glaucoma occurs most frequently in individuals over age 40. Diabetics, people with a family history of the ailment, and those who are nearsighted are at greater risk. 

Is Treatment Possible?

If diagnosed at an early stage, glaucoma can usually be controlled using prescription drops and medication. If it is not promptly diagnosed, however, it can impact a person’s vision and even result in irreversible blindness.

What Are The Symptoms?

Some types of glaucoma develop slowly and painlessly, gradually destroying a person’s vision without them even noticing. Others may present symptoms, including blurry vision, ocular pain and redness, and the appearance of “halos” or colored rings when looking at lights.

How Is It Diagnosed?

Since the symptoms are hard to detect and sometimes not present at all, it’s essential to get regular screenings. A painless procedure called tonometry measures the internal pressure of your eye. Find out how often you should be tested here.
