What is Glaucoma? Symptoms, Causes & Treatment

Glaucoma is the term given to a group of eye disorders that can affect your vision. There are several risk factors, but it is more common in older people and those with a family history of the condition.

Symptoms

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.

Causes

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.

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.
