          Abstract

          In this study of diabetic colour vision, differences in performance were found on the Pickford-Nicolson anomaloscope and the Farnsworth-Munsell 100-Hue test, between diabetics and equivalent age controls and between diabetics with retino-pathies and those with none. The discriminant function analysis used (which selects the weighted combination of the available variables) shows that the best separation into these categories (error in classification below 20%) is achieved when both colour vision variables and duration are included. Colour vision tests plus the duration variable are also useful in predicting onset of minor retinopathies in diabetics under 30 and over 60 years of age, where those patients first had no retinal damage but developed a few microaneurisms after 5 years.
