What is glaucoma?

Glaucoma is the name given to a group of eye conditions which cause optic nerve damage and can affect your vision. Glaucoma damages the optic nerve at the point where it leaves your eye.

There are four types of glaucoma, the most common of which is primary open angle glaucoma (POAG) or chronic glaucoma. If you have POAG your peripheral vision, which is the vision you have around the edge of what you are looking directly at, gradually gets worse.

There is currently no treatment to restore sight loss caused by glaucoma but treatments, such as eye drops and laser surgery, can help prevent sight loss from happening.

You can get more information and advice on glaucoma by contacting the International Glaucoma Association (IGA):
