Color vision defects in diabetic retinopathy

ABSTRACT

The association between color vision defects and diabetic retinopathy was reported by several authors. In order to study this relation 67 eyes of 40 diabetic patients were examined, also 40 eyes of 20 controls were studied. All the patients were examined ophthalmologically, fluorescein angiography was done and the colour vision was tested by Ishihara pseudoisochromatic plates and Farnworth Dichotomous test Panel D-15. 14.93% of eyes with diabetic retinopathy failed the Ishihara test, all of them showed maculopathy. 65.67% of eyes with diabetic retinopathy were color defective when tested with D-15 test. Blue-yellow defects constituted 70.45% of total color defects
