What Is a Glaucoma Test?

glaucoma - eye doctor in allentown paGlaucoma 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 so. Eye doctors can use a number of tests for eye pressure, but will, by default, 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.

How Does Glaucoma Testing Work?

A glaucoma test is usually part of a routine eye exam. Both types of glaucoma tests measure the internal pressure of the eye.

One glaucoma test involves measuring what happens when a puff of air is blown across the surface of the eye. (A puff test) Another test uses a special device (in conjunction with eye-numbing drops) to “touch” the surface of the eye to measure eye pressure.
While increased eye pressure is a key indicator of the disease, it does not necessarily mean you have a glaucoma diagnosis. In fact, the only way to detect glaucoma is to have a detailed, comprehensive eye exam that often includes dilation of the pupils. Routine eye exam not only helps in glaucoma detection but will also help to detect other eye conditions such as macular degeneration.
So “true” glaucoma testing actually involves examining the retina and optic nerve at the back of the eye for signs of the disease.

Who is at risk for Glaucoma?

Technically speaking, everybody is at risk for Glaucoma. However, there are some people who are more at risk than others.

  • African Americans are 6 to 8 times more likely than the general population to be affected by Glaucoma. Glaucoma is the second leading cause of blindness in African Americans, after Cataracts.
  • Asians are at higher risk for Glaucoma, specifically for the less common angle - closure glaucoma. The Japanese however, are at a higher risk for normal tension glaucoma
  • Hispanics over the age of 60 have a higher rate of Glaucoma
  • Anyone who has had an eye injury or bruises in the eye is at a higher risk. The most common injuries are related to baseball and boxing
  • People with severe myopia (nearsightedness), hypertension, high blood pressure, and diabetics are also at high risk for Glaucoma. Anyone over the age of 60 and anyone with a family history of Glaucoma is at a high risk as well.
