Rotating grating treatment of amblyopia with and without eccentric fixation.

Treatment of amblyopia with and without eccentric fixation using short term occlusion and rotating gratings was analyzed in a controlled study. A control group (n = 18) viewed a blank rotating disc for 15 minutes once a week for ten weeks while the treatment group (n = 20) observed rotating gratings for the same time period. Both groups performed visually guided tasks to maintain treatment interest. Visual acuity was analyzed before and after each treatment session using a multiple Landolt ring chart. Data were gathered in a double masked manner. Analysis did not reveal a statistically significant improvement of visual acuity with rotating grating therapy for treating amblyopia with or without eccentric fixation.
