Are There Different Types Of Glaucoma?
Triad Eye Medical Clinic Frequently Asked Questions PageSimple or chronic open-angle glaucoma: This accounts for the majority -- about 90 percent -- of cases. It progresses slowly and often goes unnoticed for many months or years, causing a gradual deterioration of vision. This type of glaucoma typically responds well to treatment. Therapy is usually continued for life so that the pressure is kept under control, helping to prevent loss of vision. In a few cases, surgery is required to allow the fluid to pass more freely from the eye.
Related QuestionsEye care & ophthalmologic knowledge base, eye articles, ...The risk of developing chronic open-angle glaucoma increases with age. The drainage angle of the eye becomes less efficient over time, and pressure within the eye gradually increases, which can damage the optic nerve. In some patients, the optic nerve becomes sensitive even to normal eye pressure and is at risk for damage. Treatment is necessary to prevent further vision loss. Typically, open-angle glaucoma has no symptoms in its early stages and vision remains normal.Related Questions

Cataract Surgery California | Diabetic Retinopathy Santa Ros...Glaucoma is a disease that results in the damage of optic nerve due to high eye pressure.

Related QuestionsWhat is glaucoma?
Oklahoma City, Oklahoma Eye Surgery - FAQGlaucoma is an eye disease in which increased intraocular pressure (that is, too much fluid inside the eye) causes vision loss and blindness by damaging the optic nerve.

Related QuestionsTriad Eye Medical Clinic Frequently Asked Questions PageGlaucoma is a condition in which the pressure of fluid in the eyeball is abnormally high -- higher than the eye can tolerate over a long period of time. Most ophthalmologists agree that when pressure in the eye -- referred to as intraocular pressure -- is higher than normal, the risk of pressure-related damage significantly increases. Glaucoma is caused by a buildup of the fluid -- aqueous humor -- that circulates within the eye.Related Questions
