How To Read A Visual Field Test
Visual field test: In stable glaucoma, normally done once a year to verify that no change for the worse is occurring. If so, treatment will be intensified. If your glaucoma is unstable, or a change in the optic nerve is noted, a visual field is done at that time even if already done that year. Visual fields are measured besides the optic nerve cup/disc ratio, intraocular pressure, and nerve fiber layer. ...Read moreSee 1 more doctor answer
Have Macular pucker causes white to appear gray. Also have glaucoma. Will visual field test be inaccurate because background is gray instead of white.
Likely to be fine: There can be multiple conditions in an eye at one time, and when this is the case a visual field may be a bit off from it's full potential. But it can still give useful information. In your case, if it is inaccurate, some changes can be made to the settings of the test to make it easier.

Is it possible to get accurate visual field test with macular pucker decline in visual acuity, lights less bright & white computer screen looking gray?
Usually it is fine: You have defects in the central visual portion of your field of view - an area poorly outlined by most field testing devices. Field tests will define major defects which largely will register from the peripheral areas tested. Have you had a field tested in the past? Is there some condition being sought for with a field.? Your ophthalmologist would not order a field if he doubts the result. ...Read more
Two eye drs. Looking at visual field test result. One dr says it is normal & other says there's peripheral vision loss. Why the difference of opinion?
Interpretation: Interpretation of visual field change is somewhat subjective. As many as 5 cosequetive visual fields are necessary to show change over time. Peripheral changes can have a lot of "noise" in deciding whether or not it is real defect or not. Repetition of field testing and confirmation of defect over time is more accurate. Even then, there are many factors that can interfere in vf assessment. ...Read more
