Oct 31, 2023 · A visual field test measures how well you can see above, below, and on either side of you. This test can help diagnose diseases of the eye, optic nerve, and central nervous system. Your vision relies on your retina, optic nerves, and your brain. Vision loss occurs due to diseases that affect any part of this pathway.
Apr 4, 2023 · A visual field test is a simple and painless test an eye care provider gives you to diagnose or monitor various eye conditions. A visual field test measures two things: How far up, down, left and right your eye sees without moving (when you’re looking straight ahead). How sensitive your vision is in different parts of the visual field, which ...
- Confrontation visual field test. A common way for your doctor to screen for any problems in your visual field is with a confrontation visual field test.
- Automated static perimetry test. To check for a suspected eye problem or monitor the progress of an eye disease, your ophthalmologist will rely on more specific tests to measure how you see objects in your field of vision.
- Kinetic visual field test. In some cases, you may have a test called kinetic visual field testing. While it is similar to the perimetry testing process described above, the kinetic test uses moving light targets instead of blinking lights.
- Frequency doubling perimetry. Another way your ophthalmologist can assess loss of vision is using something called frequency doubling perimetry. It uses an optical illusion to check for damage to vision.
Dec 12, 2015 · Visual Fields: Introduction. December 12, 2015. The study and interpretation of visual fields is a very important part of ophthalmology and used for many different conditions, ranging from glaucoma (its most common use) to localizing neurological defects, and even to evaluate some retinal diseases. There are many different methods for assessing ...

A visual field test measures your entire scope of vision, both central and peripheral (side), mapping the visual fields of each eye individually. This allows an eye healthcare professional to check for blind spots or areas where your vision is less strong. There are a number of different visual field tests used to measure either your peripheral ...

Jun 10, 2022 · Comparing Algorithms. A number of different algorithms beside SITA are available for use in visual field testing. Stuart K. Gardiner, PhD, a senior scientist at Devers Eye Institute in Portland, Oregon—who has worked with many of them—says that the GATE (German Adaptive Threshold Estimation) algorithm, available on the Octopus perimeter, is similar to SITA.
