Glaucoma is an eye disease that damages the optic nerve. The optic nerve transmits visual information from the eye to the brain. Cataracts are usually, but not always, the result of abnormal pressure inside the eye. Over time, increased pressure can cause the loss of optic nerve tissue and eventually lead to vision loss or even blindness. If this disease is diagnosed early, its progress can be prevented
Primary open-angle glaucoma, the most common type of glaucoma, has no symptoms other than gradual vision loss. The presence of blind spots in the lateral vision angle, the formation of direct vision in both eyes, or the tunnel-like vision angle in advanced stages, can be its symptoms.
