Today I had an appointment at the Kaiser optometry office for a visual field test. This test measured my peripheral vision. The visual field test helps the ophthalmologist monitor any loss of vision and diagnose eye problems and disease. I had a diabetic eye exam a couple of weeks ago and the doctor wanted this follow-up test done.
The test was performed by a technician. I sat in front of a machine with my chin and forehead touching the machine. The eyes are tested one a time, with the non-testing eye covered by a patch. I had to focus on a small light near the top of the screen. I had a clicker in my hand. A computer displayed quick pinpricks of light and I clicked the button whenever I saw a light. The computer then automatically mapped and calculated my visual field.
I will find out the results of this test in a week or so. The test was frustrating because when I blinked, I sometimes missed the light being displayed. I hope I did well on this test, which would show that my peripheral vision is fine. Loss of peripheral vision is an early sign of glaucoma. Whatever the results, I will have to learn to deal with it!
This machine is similar to the one used in the vision field test.
