Glaucoma continues to be a major public health problem. It is the second leading cause of blindness worldwide after cataracts. In the United States, primary open-angle glaucoma is the most
common form of glaucoma and is the leading cause of irreversible blindness in African Americans. This disease is typically without symptoms until advanced visual field loss occurs.
Some of the risk factors for primary open-angle glaucoma include elevated intraocular pressure, advancing age, family history, African ancestry, myopia, and presence of certain systemic
diseases. The precise mechanism of primary open angle glaucoma remains unclear and is currently an active focus of research.
At present, all our treatment strategies are directed at lowering intraocular pressure. Initial treatment is usually started with topical or oral medications. However, with progressive
damage, laser surgery may be considered, followed by glaucoma surgery, or glaucoma drainage implant.
