Glaucoma Testing
What Is a Glaucoma Test?
Glaucoma is the generalized name for a group of eye diseases that damage the optic nerve of the eye, preventing the eye from sending accurate visual information to the brain. Glaucoma tests are designed to test your eyes for one of the key symptoms of the disease—increased eye pressure—however only a comprehensive eye exam can reveal whether or not you have glaucoma. Increased pressure inside the eye is often a key indicator of glaucoma, though not exclusively. Eye doctors can test for eye pressure and will check for signs of glaucoma as part of a detailed examination of the retina—the light sensitive area at the back of the eye responsible for processing images. A damaged optic nerve is seen in the photo at right.
How Does Glaucoma Testing Work?
An eye pressure screening is measured by a technician in a routine, comprehensive eye exam. If abnormalities are noted, the doctor will recheck the pressure in the examination lane. A screening method of testing pressure involves a very light puff of air. To accurately measure an eye that has glaucoma, a measurement called Goldman tonometry is performed. This is performed by the doctor and is very easy. A mild numbing drop is placed in the eye and the pressure is measured with no discomfort or wait.
