Perimetry tests are used to find certain patterns of vision loss, are useful for finding certain types of eye diseases, and discovering early changes in vision caused by nerve damage from glaucoma. The test is done by having the patient look inside a bowl-shaped instrument called a Perimeter. Lights flash as the patient stares at the center of the machine, and the patient presses a button each time they see a flash, where results are then recorded by a computer.
