Glaucoma

Glaucoma is a group of eye diseases that damage the optic nerve, the part of the eye that sends visual information from the retina to the brain. This damage is often (but not always) caused by increased pressure inside the eye, known as intraocular pressure (IOP).

👁️ Key Facts:

• Main cause: Usually elevated eye pressure, though some people develop glaucoma even with normal pressure.

• Effect: Gradual loss of peripheral (side) vision, which can progress to total blindness if untreated.

• Permanence: Vision loss from glaucoma is irreversible, but early detection and treatment can slow or stop progression.
