PURPOSE: We consider the hypothesis that proliferative diabetes produces selective lossof colour channels. We also consider the possibility that laser treatment for this condition does not affect macula function. METHODS: We tested for the possibility of a selective colour channel involvement in 35 eyes of 33 cases of proliferative diabetes by considering the outcomes of saturation and hue testing before and after pan-retinal photocoagulation (PRP). Saturation testing was achieved with the Sahlgren Saturation Test (SST) and hue testing was via the Farnsworth-Munsell 100 (FM100) hue test. Our results were compared to a recent model1 that was developed to predict the saturation processing of d..
