Plaquenil oct of macula Chloroquine resistant plasmodium falciparum treatment Chloroquine peak plasma concentrations Visual fields. In early cases of Plaquenil toxicity, an early indicator of damage is the appearance of a paracentral scotoma seen on automated visual field testing in the absence of fundus changes. 18 Each of the testing strategies can be used to detect early toxicity changes, but the presentation of the visual field effects will vary. Due to the central area being depressed in the 24-2 and 30-2 testing strategies, it is difficult to discern the central 2-degree field of sparing seen in the. Visual field testing actually maps the visual fields to detect any early or late signs of glaucomatous damage to the optic nerve. In order to find and follow glaucoma, visual fields are measured by a computer one eye at a time. One eye is covered and the patient places his or her chin in a type of bowl. Here, we’ll only talk about the Humphrey visual field perimeter, which is used for 99% of visual field tests. It’s an automated, static perimeter unlike Goldmann kinetic perimetry which requires a human operator, and uses a moving target. The Humphrey uses fixed points of light which are shown at different intensity levels.

The visual field test is a subjective measure of central and peripheral vision, or “side vision,” and is used by your doctor to diagnose, determine the severity of, and monitor your glaucoma. The most common visual field test uses a light spot that is repeatedly presented in different areas of your peripheral vision. Helpful, trusted answers from doctors Dr. Workman on field vision test failed The fixation losses are related to the reliability of the test. Some peripheral shading is within normal limits on the test.
