Oct 19, 2015 · Contrast sensitivity testing can also tell the clinician about the patient’s dominant eye and their overall quality of vision. Finally, contrast sensitivity testing helps clinicians to …

It is critical to apply test procedures that are robust to non-pathologic influences on flicker sensitivity, and to implement test procedures that are best designed to provide stable, …

The FDT procedure first attracted interest as a clinical diagnostic test procedure based on the fact that flicker sensitivity and flicker perimetry has been found to be useful for evaluation of …

In the search for a sensitive diagnostic examination, many clinical tests have been proposed such as achromatic automated perimetry (AAP), short-wavelength automated perimetry (SWAP), …

Color vision testing, flicker sensitivity, contrast sensitivity, pupillary responses and motion testing are some of the other methods of quantitating vision. Perimetry is the systematic …

Oct 19, 2015 · This is because functional vision takes into account factors such as loss of contrast sensitivity, photophobia, and/or ocular motor problems. Slide 13 Here you see a variety of …

For example, contrast sensitivity, flicker, motion, and colour stimuli are used to quantify the visual field. Such stimuli can be presented with or without prior cueing.

Contrast sensitivity was measured with the LH test at a test distance of 50 cm, measuring VA at four contrast levels, 10%, 5%, 3% and 1.5%. These tests were performed before and 65 …

The test will then present a final stimulus at maximum (100%) contrast and if it is not detected, the sensitivity loss for that location is classified as ‘severe’ loss of sensitivity. The second …

An often overlooked source of poor test results are insufficient instructions to the patient. Large differences in sensitivity can occur with seemingly small differences in instruction sets. Most …
