What are the symptoms of glaucoma?

The main symptom of glaucoma is vision loss, especially loss of peripheral vision. However, half of all people who experience loss of vision caused by glaucoma are not aware they have the disease. By the time they notice loss of vision, the eye damage is severe.

Rarely, an individual will have an acute (sudden or short-term) attack of glaucoma. In these cases, the eye becomes red and extremely painful. Nausea, vomiting and blurred vision may also occur.
