Glaucoma is usually picked up during a routine eye test, often before it causes any noticeable symptoms. Other tests are usually needed afterwards to diagnose and monitor the condition.


Glaucoma is a common eye condition where the optic nerve, which connects the eye to the brain, becomes damaged.


Symptoms of glaucoma can include blurred vision or seeing rainbow-coloured circles around bright lights. Both eyes are usually affected.


Your age, ethnicity, family history and some medical conditions can increase your chances of getting glaucoma.


Treatment for glaucoma will depend on your symptoms. It can include eye drops, laser treatment and surgery.
