At Dr. Krietlow & Associates, we use state of the art technology in order to offer our patients the very best in eye care. At our Blaine location, we have recently acquired the most technologically advanced field analyzer for glaucoma diagnosis and management.
A visual field test measures how much ‘side’ vision you have. It is a straightforward test, painless, and does not involve eye drops. Essentially lights are flashed on, and you have to press a button whenever you see the light. Your head is kept still and you have to place your chin on a chin rest. The lights are bright or dim at different stages of the test. Some of the flashes are purely to check you are concentrating.
Each eye is tested separately and the entire test takes 15-45 minutes. Your optometrist may ask only for a driving licence visual field test, which takes 5-10 minutes. If you have just asked for a driving test or the clinic doctor advised you have one, you will be informed of the result by the clinic doctor, in writing, in a few weeks.
Validated by more than 25 years of research, design and clinical experience, the Humphrey® Field Analyzer (HFA™) is the accepted standard of care in glaucoma diagnosis and management, as well as detecting stroke and brain tumors.
Zeiss has now come out with the latest model, the Humphrey® Field Analyzer 3 with Liquid Lens technology, and we have it!
Occasionally the manual test has to be used, a Goldman. For each test you have to look at a central point then press a buzzer each time you see the light.
