With early detection and treatment, loss of sight can often be prevented.
Glaucoma is a disease in the part of the eye that carries the images we see to the brain, called the optic nerve. It is made of many nerve fibers and will cause blind spots when damaged. Most blind spots go undetected until significant damage occurs.
Glaucoma has two common types: primary open-angle and angle-closure. Regular eye exams can make all the difference in diagnosis and detection. Symptoms of primary open-angle glaucoma do not appear until permanent damage has occurred.
