Glaucoma is an eye condition where the optic nerve, which connects the eye to the brain, becomes damaged by the build-up of pressure in the front part of the eye caused by fluid build-up.

There are various different types of glaucoma with the most common being angle glaucoma, which tends to develop slowly over many years as the drainage channels in the eye gradually clog up. This causes the increase in fluid and pressure which then damages the optic nerve.

Other types of glaucoma include: Acute angle closure glaucoma, a rare form where the eye pressure increases very suddenly, secondary glaucoma as a result of another eye condition, operation or injury, and congenital glaucoma, an incredibly rare condition that affects young babies. Most types of glaucoma have no symptoms, so a regular eye test is the only way to know you have the condition.

Glaucoma can affect people of all ages but it is most common in the elderly.
