Your optometrist can use a variety of tests for glaucoma, including a visual field test, a corneal thickness test, an angle test, optic nerve imaging, or an eye pressure check.
The visual field test allows your doctor to diagnose if you have lost any field of vision from glaucoma, how much you have lost, and the rate of glaucoma progression.
The eye pressure test is called tonometry. In the most common tonometry test, a tiny instrument contacts the surface of the eye after it is numbed with eyedrops. It is a quick and painless test for glaucoma.
Noninvasive glaucoma imaging tests may be used to monitor glaucoma progression. During this test, your pupils are dilated using eyedrops and the doctor photographs your optic nerve with a digital camera.
