Glaucoma Prevalence.

Glaucoma is a group of eye diseases that gradually steals sight without warning
and often without symptoms. Vision loss is caused by damage to the optic nerve. This
nerve acts like an electric cable with over a million wires and is responsible for
carrying the images we see to the brain. It was once thought that high intraocular pressure (lOP) was the main cause of this optic nerve damage. Although lOP is clearly a risk factor, we now know that other factors must also be involved because even people with "normal" lOP can experience vision loss from glaucoma. The diagnosis of glaucoma is a gray area that practitioners struggle with. When do we consider the patient to have glaucoma? And who is most at risk to develop glaucoma? These are questions that I would like to have answered. There are many studies out there that provide bits and pieces of glaucoma prevalence, incidence, and risk factors. This research paper will bring many studies together to clarify the prevalence, incidence, and risk factor .
