Glaucoma is an eye disease that involves a build-up of fluid pressure in your eye. If this pressure becomes too great, it can permanently damage your optic nerve, leading to serious visual impairment or even blindness. Diagnosing and controlling the disease early is important in order to prevent vision problems, but according to the American Academy of Ophthalmology, around 2 million people in the United States are not even aware they have glaucoma.

No test can replace a professional evaluation performed by an experienced ophthalmologist, but the FDA has recently approved an at-home glaucoma test provided by the Perisiat Group, with a 90% accuracy rating.

You can perform this test from your computer by following the steps below:

  1. Go to the Peristat website to begin the test: http://www.keepyoursight.org
  2. Click “Login or Register to Take Test” and follow the instructions. Choose the Peristat Visual Field Test.
  3. Keep the ambient lighting in your room dim, and make sure you computer monitor has no glare.
  4. Sit approximately two feet from the screen, and select an eye to test. Cover the other eye with your hand. If you wear glasses or contact lenses, leave them on.
  5. Focus on the white counter in the center of the screen; do not look at any other part of the screen. Slowly move your head closer to the screen until the flashing green light in your peripheral vision disappears.
  6. Press any key or the left mouse button. Whenever a gray dot flashes onto your screen, press any key or the left mouse button again to document it.
  7. In order to obtain your results, you will need to pay a fee. After a professional review, your results will be emailed to you. This usually takes around 24 hours.
