Primary Open Angle Glaucoma (P.O.A.G.)
Primary open angle glaucoma (often referred to by the acronym P.O.A.G.) is the most common type of glaucoma in the United States. Worldwide, estimates indicate that 67 million people may be affected by P.O.A.G. Among them, about 7 million people are blind in both eyes from P.O.A.G., which makes it the second leading cause of blindness. Primary open angle glaucoma is defined by a clearly open anterior chamber angle in a patient with sufficiently characteristic features of glaucoma to make the diagnosis. Further, P.O.A.G. may only be diagnosed in the absence of any other ocular condition that is known to cause glaucoma.
