A visual field test measures your peripheral vision, or how well you can see above, below and to the sides of something you’re looking at. It’s also called a perimetry test. It can diagnose or monitor various eye conditions, such as glaucoma, stroke and macular degeneration. Learn about the types, preparation and results of this test.
Oct 31, 2023 · A visual field test measures how well you can see above, below, and on either side of you. It can help diagnose diseases of the eye, optic nerve, and central nervous system that affect your vision.
Feb 13, 2024 · Visual field is the area that you can see at one time without moving your eyes. Learn why and how to test your visual field, and what diseases or disorders it can reveal.
- 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.
Definition. The field of vision is that portion of space in which objects are visible at the same moment during steady fixation of gaze in one direction. The monocular visual field consists of central vision, which includes the inner 30 degrees of vision and central fixation, and the peripheral visual field, which extends 100 degrees laterally ...
Jan 20, 2024 · January 20, 2024. What is the visual field? The visual field is essentially the area of space that can you can see at the same time. In other words, it refers to your field of vision or how far out peripherally you are able to see without moving your eyes or head.
The visual field is "that portion of space in which objects are visible at the same moment during steady fixation of the gaze in one direction"; [1] in ophthalmology and neurology the emphasis is mostly on the structure inside the visual field and it is then considered “the field of functional capacity obtained and recorded by means of perimetry”.
