Glaucoma is the term given to a group of eye disorders that can that can damage nerves in your eye when there is too much fluid pressure inside your eye when there is too much fluid pressure inside your eye. There are several risk factors. if you ignore it or go untreated, glaucoma can lead to blindness but it is more common in older people and those with a family history of the condition.
It is common for people not to experience any symptoms at first, but if left untreated glaucoma can affect your eyes and can lead to permanent vision loss. It is therefore important to have regular eye examinations so that it can be detected as early as possible.
Your eye constantly produces a watery fluid called aqueous humor. When that fluid doesn't drain properly, pressure inside your eye builds up and puts pressure on the optic nerves. Glaucoma occurs when the pressure inside your eye is sufficiently high to damage the structures at the back of your eye leading to nerve damage. It usually affects both eyes, but is likely to affect one eye more quickly than the other.
The two major categories of glaucoma are open-angle glaucoma and narrow-angle glaucoma. There are several subcategories of both, which your eye care professional can diagnose and treat.
Damage to the eye caused by glaucoma cannot be reversed, but early diagnosis and treatment with medication, laser eye treatment or surgery can minimise further vision loss.
