Although anyone can get glaucoma, some people are at higher risk of glaucoma.
The following are risk factors:
Family history of glaucoma
Being over the age of 60
History of eye injury
High blood pressure
There are three primary types of glaucoma:
Open angle: The eye’s drainage canals get clogged over time, which causes pressure to build. There are few symptoms and no pain. The disease is usually advanced by the time it is detected.
Acute angle closure: The eye’s drainage canals get clogged suddenly and the pressure builds quickly. Onset is sudden, with blurred vision, severe eye pain and rainbow circles appearing around bright lights. There are no warnings. It is a medical emergency.
Normal tension: Eye pressure is normal, but the optic nerve is damaged. There are few symptoms and no pain. The disease is usually advanced by the time it is detected.
