The ultimate visual outcome depends on the severity of the disease at diagnosis, the presence of other associated ocular abnormalities, response to surgical treatment, and success in controlling IOP on follow up. Those at risk are advised to have a dilated eye examination at least once a year.

Genetic Etiologies of Glaucoma

However, the major risk factor for most glaucomas and the focus of treatment is increased intraocular pressure. Several theories exist on its exact etiology. The identification of the molecular events responsible for glaucoma has been difficult because of a general lack of knowledge about the cellular and biochemical events that are necessary for the normal regulation of IOP and retinal ganglion cell function.
