[Nyctometry and flicker discrimination in diabetic retinopathy].
98 diabetics and 34 healthy probands were recruited for ophthalmoscopic evaluation of the retina with a fundus camera, and for functional tests of the retina using a flicker frequency analyzer and a nyctometer. One year later, funduscopic evaluation of the ocular fundal state was carried out, and the results compared with the original baseline set of functional parameters. In the control group of healthy probands, a result only partially duplicated in the group of diabetics. An age-corrected comparison of the two groups revealed no difference between the diabetics and the healthy probands. Attempts were made to identify groups displaying significant differences in retinal performance as evaluated by the procedures mentioned above, but neither taking duration of diabetes as a criterion, nor selecting for differences in the course of diabetic retinopathy enabled the identification of such groups. A decrease in retinal performance was seen in very severe stages of diabetic retinopathy. These functional tests are not suitable in the early stages of diabetic retinopathy for defining that group of high-risk patients in which rapid progression of diabetic retinopathy is to be expected.
