          Abstract

          Dark adaptation in diabetics was recorded with Goldmann-Weeker's adaptometer and analysed according to the stages of retinopathy by Scott. Dark adaptation curves in diabetics were divided into three groups; normal dark adaptation; subnormal one which showed normal first curve of dark adaptation and impaired second curve; abnormal dark adaptation which showed impaired dark adaptation in the whole course. The cases with normal dark adaptation were found to be few in the stages Ia, II and IIIa of retinopathy. Subnormal dark adaptation was rarely found in the stages Ia, II, IIIa and IIb of retinopathy. Abnormal dark adaptation was recorded in most patients with diabetic retinopathy and found in all th stages of retinopathy. A 5% level of significance was statistically recognized in the thresh old at 35 min after light adaptation between the stages IIIa and IIIb of retinopathy. From this viewpoint, significance in severity of diabetic retinopathy was discussed.
