Glaucoma is a group of eye conditions that damage the optic nerve, the connection between the eye and the brain. The optic nerve is responsible for sending visual information from the eye to the brain. Glaucoma can lead to a loss of vision and even blindness if it is not treated.
There are several different types of glaucoma, but the most common type is primary open-angle glaucoma. This type of glaucoma develops slowly and often has no symptoms in the early stages. As the condition progresses, people may experience: blurred vision, blind spots in their peripheral vision and vision loss.
