# What is glaucoma?

Glaucoma is a group of eye conditions in which the optic nerve is damaged, often in association with raised eye pressure. Without treatment it can lead to gradual, irreversible loss of vision.

## Types and symptoms

Primary open-angle glaucoma typically causes slow loss of peripheral vision with no early symptoms, while angle-closure glaucoma can present suddenly with pain and redness. Many people are diagnosed during routine eye checks before noticing problems themselves.

- Family history and age increase the risk of glaucoma
- Regular pressure checks and optic nerve assessment are important
- Treatment aims to lower eye pressure with drops, laser or surgery
- Vision that is lost cannot usually be regained, so early detection matters
