Glaucoma
The optic nerve of the eye carries neural images to the brain. Glaucoma is a condition in which the optic nerve becomes damaged. Glaucoma damages nerve fibers, causing blind spots to develop.
Damage to the optic nerve is permanent and can lead to vision loss. Most people who have glaucoma do not notice any symptoms early on in the disease. Most people notice no symptoms until late in the disease when vision become impaired.
Most cases can be managed with eye drops. Some cases require laser treatment or even an implant that can be placed at the time of cataract surgery.
