Glaucoma Q & A

What is glaucoma?

Glaucoma is a disease that damages your optic nerve if left untreated. Your optic nerve connects your eyeball to your brain, sending messages so you can interpret the images you see. When this nerve becomes damaged, you may experience blurry vision, blind spots, or even permanent blindness.

Although the exact cause of glaucoma is unknown, the disease usually occurs when the fluid in your eye builds up and increases inner eye pressure to an unhealthy level. Although glaucoma is the leading cause of blindness in people over 60 years old, blindness can usually be prevented with early detection and effective glaucoma treatments. This is one reason why annual eye exams are critical to preventing blindness from glaucoma.

What are the symptoms of glaucoma?

Since many types of glaucoma have no symptoms or warning signs, you may not realize you have the disease until you incur damage to your eyesight. The two main types of glaucoma are open-angle glaucoma and acute angle-closure glaucoma, and symptoms include:

Open-angle glaucoma symptoms

  • Tunnel vision in advanced stages
  • Patchy blind spots in your peripheral or central vision, often in both eyes

Acute angle-closure glaucoma symptoms

  • Sudden or severe eye pain
  • A severe headache
  • Sudden blurry vision
  • Red eyes
  • Nausea and vomiting
  • Halos around lights

If you experience the symptoms of acute angle-closure glaucoma, seek immediate emergency eye care, as the condition can cause blindness if not treated as soon as possible.

Open-angle glaucoma symptoms develop more gradually than acute angle-closure glaucoma. Open-angle glaucoma is the most common form of the condition and occurs gradually when your eye doesn’t drain fluid as quickly as it should, similar to a clogged drain in which the water flows very slowly. Most symptoms are painless, and you may not notice a problem until you begin to have trouble seeing clearly.

How does an optometrist diagnose and treat glaucoma?

During your annual eye exam, Dr. Solan conducts several tests for glaucoma, including one that measures the pressure inside your eyes. He also measures the thickness of your cornea. If he detects abnormal eye pressure, he may prescribe medicated eye drops that help lower your eye pressure so the disease cannot progress as quickly.

Additionally, depending on the type of glaucoma you have, there are laser procedures and surgical treatments that help drain the fluid from your eye and alleviate abnormally high eye pressure. There is no cure for glaucoma, so early detection maximizes your treatment options and enables you to preserve your eyesight for as long as possible.

If you have a family history of glaucoma, you may be at risk. Call to schedule an eye exam or book online.
