Glaucoma

What Is Glaucoma?

Glaucoma is like having too much pressure in your eye - it can damage your optic nerve and cause vision loss. It's often called the "silent thief of sight" because it can cause permanent vision loss without warning.

Your eye produces a clear fluid called aqueous humor that nourishes the eye. Normally, this fluid drains out of the eye. In glaucoma, the fluid doesn't drain properly, causing pressure to build up and damage the optic nerve.

Types of Glaucoma

Open-angle glaucoma - Most common type, develops slowly Angle-closure glaucoma - Less common, can develop quickly Normal-tension glaucoma - Occurs with normal eye pressure Congenital glaucoma - Present at birth Secondary glaucoma - Caused by other diseases or medications
