Treatment for amblyopia with rotating gratings and subsequent occlusion: a controlled study

In a controlled study, the amblyopic eye of a group of 12 patients was stimulated in accordance with the original method of Campbell et al. (1978), using gratings, and a control group of 10 patients with black and white pictures. As in other controlled studies, no specific benefits ensued from the use of gratings. In both groups only slight visual improvements resulted, probably due to the repeated testing of visual acuity and nonspecific effects of short-term occlusion. A clear improvement in visual acuity and fixation behaviour was only observed after subsequent long-term occlusion.Presented in part to the Deutsche Ophthalmologische Gesellschaft in Kiel, September 1980.Supported by the Deutsche Forschungsgemeinschaft, SFB 7o, B4.
