We quantitated the aqueous flare intensity in 148eyes with preproliferative diabetic retinopathy(PPDR). The eyes were divided into 3 subgroups:mild type showing soft exudates but no apparentnonperfusion, moderate type with soft exudates andnonperfusion, and severe type with additionalvenous beading. The aqueous flare become moreintense from mild through moderate to severe type.The difference among the 3 groups was significant (p<0.05). We also quantitated the aqueous flareintensity in 59 eyes with simple retinopathy and 79eyes with proliferative retinopathy. The flare inten-sity in simple retinopathy was significantly less than in moderate or severe types of PPDR (p<0.002). No difference was present between simpleretinopathy and mild type of PPDR. Flare intensityin proliferative retinopathy was higher than insimple retinopathy and moderate type of PPDR (p <0.001). No difference was present betweensevere type of PPDR and proliferative retinopathy.Above findings seemed to show the adequacy of thepresent method of subclassification of PPDR.
