Sine-wave Grating Testing & Multiple Sclerosis :: Case Study The chart below demonstrates the visual sensitivity between eyes of a multiple sclerosis patient not found using Snellen acuity. In this case, the sine-wave grating test detects a significant contrast loss. *This patient has normal Snellen visual acuity.

"Unequivocal results were obtained from the one control subject who had a (marginal) medium frequency notch in the contrast sensitivity curve. This subject had no appreciable difference in discrimination between left and right eyes for the unfiltered broadband letter pair, suggesting that, at viewing distances for which low cycle/width information fell into the notch, he was able to use the remaining high cycle/width information for letter discrimination, when it was available." (Quote, in references, see: Regan D, et al. Contrast sensitivity and Snellen acuity in multiple sclerosis. Figure, in references, see: Ginsburg AP. Spatial filtering and vision: implications for normal and abnormal vision.)
