    Abstract:
    The effects of an aldose reductase inhibitor (M79175) on electroretinogram (ERG) oscillatory potential abnormalities was studied in rats with streptozotocin fructose-induced diabetes. The ERG oscillatory potential was recorded under scotopic conditions without general anesthesia in the diabetic rats, before and 4, 8 and 12 weeks after administration of M79175. The ERG tracings were analyzed for peak latencies, peak intervals and amplitudes; the peak latencies and intervals were prolonged and the amplitudes were reduced in untreated diabetic rats, but the prolongation of the peak latencies and intervals were suppressed in diabetic rats receiving M79175. The amplitudes were reduced in the treated rats as in the untreated rats. The results of this investigation suggest that M79175 is effective to suppress progression of diabetic retinopathy in its early stage.
