Glaucoma Test

A glaucoma test is a routine part of a complete eye exam. There are five different tests commonly used for glaucoma detection. Early detection of glaucoma is necessary if patients want to protect their eyes against permanent damage from glaucoma. Before forty years old, individuals should get glaucoma tests done every two to four years. Between forty and fifty-four years old, that period changes to every one to three years. From fifty-five to sixty-four years old, the period is every one to two years. Since individuals over sixty-five years old are at a much higher risk for glaucoma, they should get a test done every six to twelve months. A tonometry test is used to examine the pressure of the inner eye. A dilated eye exam allows the doctor to determine the color and shape of the patient's optic nerve. A visual field test determines whether individuals have a complete field of vision. To measure the thickness of the cornea, the doctor will use a pachymetry test. Finally, a gonioscopy determines the angle at which the iris meets the cornea inside the eye.
