Glaucoma
Glaucoma is an eye disease that gradually steals sight without symptoms, pain, or warning. Typically characterized by high pressure within the eye, the passages that allow the normal fluid in the eye to drain become clogged and blocked. This results in the amount of fluid in the eye building up and causing increased pressure inside the eye. This increased pressure damages the optic nerve, which connects the eye to the brain. The optic nerve is the main carrier of vision information to the brain. Damage to it results in less information sent to the brain and a loss of vision. Glaucoma is one of the most common and severe eye disorders of people over 40. Early treatment is vital, or the condition can ultimately lead to blindness.
Chronic glaucoma has many times been referred to as the “Silent thief of sight” as there are no warning signs. Roughly half of Americans who have chronic glaucoma do not know it. Glaucoma reduces your peripheral vision so slowly, that once you notice it, permanent damage is done.
Narrow-angle glaucoma, can produce sudden symptoms such as, headaches, eye pain, halos around lights, red eyes, nausea, vomiting, and vision loss. These attacks may last for a few hours, and go away, then return again, each taking a part of your field of vision.
At this time there is no cure for glaucoma. The best way to prevent vision loss from glaucoma is early diagnosis and treatment.
