[Color vision under different luminosity in various fundus diseases].
Reports on the utilization of the color vision test as a method for detecting early abnormality in fundus diseases have been published. The author performed the 100-hue test at five luminous stage levels set between 10 and 2000 lux in cases of glaucoma, diabetic retinopathy and central chorioretinopathy. The progressive degree of each disease and the level of disorder seen in color vision were assessed comparatively at each luminous level to determine adequate luminosity for performing the 100-hue test. For classification of the degree of progression in each disease, visual acuity, visual field and C/D ratio were used for glaucoma. Visual acuity, type of retinopathy and the period of contracting the disease were used for diabetic retinopathy, and visual acuity was used for central chorioretinopathy. As a result, the total error score in the 100-hue test closely correlated to the degree of progression of each disease and the luminosity for performing the most effective 100-hue test was found to be 100 lux.
