The "no maculopathy group" (38 patients) was followed for more than four years. Maculopathy developed in five of them and photocoagulation treatment was indicated. Neither alteration in color sensation nor the size of the macular capillary bed occlusion gave any sign of the development of maculopathy. The "maculopathy group" (100 patients) was evaluated for color sensation and the size of the macular capillary bed occlusion. In color sensation, no significant difference was found between those with decreased visual acuity after photocoagulation and those with unchanged visual acuity. However, marked differences in the size of the macular capillary bed occlusion between the two groups were confirmed. The color sensation test was able to reveal abnormality even in the earliest phase of maculopathy and was useful for detecting the presence of early macular edema. However, it did not seem to be effective in predicting the visual prognosis.
