A family history of glaucoma is an important risk factor. Patients are usually not aware of early glaucomatous visual field loss. Myelinated nerve fibers close to the optic disc. Areas of scarring adjacent to the disc. Hard exudates scattered in the macula.
Most attacks are painless.
The anterior chamber of an affected eye is usually very deep. The intraocular pressure is usually only minimally elevated. Laser iridotomy is generally effective in relieving pupillary block. Angle closure glaucoma is not considered to be an emergency. The goal of treatment is to reduce the intraocular pressure in order to prevent further visual loss.
