Abstract
Single letter and linear acuity (near and distance) and contrast sensitivity were measured in 15 amblyopes (ages 5 to 12) before, during, and after four weekly 7 min sessions of CAM treatment. Six of the children, however, played games over a homogeneous grey disc having the same space-averaged luminance as that of the striped stimuli. Experimental and controls results were indistinguishable. In a few subjects from both groups, contrast sensitivity and slight linear acuity improvement was observed. We conclude that these vision changes can be attributed to the short-term occlusion experienced by all subjects during treatment and that grating stimulation did not contribute to this improvement.
