Abstract

In cross sectional fashion we recoreded the cone response in 98 adult diabetics and 20 normal controls according to the recommendation by the International Society for Clinical Electrophysiology of Vision. The photopic oscillatory potentials were extracted from the cone response by highpass filtering. The clear media and attached retina were criteria for inclusion in this study. The data were statistically analyzed expecting that this procedure may provide a feature that could have some clinical significance. The analysis of variance demonstrated that the summed amplitude of the oscillatory potentials, and second oscillatory potential amplitude were the most sensitive parameters to the diabetic retina. A timing delay in the first oscillatory potential wavelet, and a reduction in the second oscillatory potential amplitude and the summed amplitude of oscillatory potentials were the commonest abnormalities. Hence, the second oscillatory potential amplitude and the summed amplitude of oscillatory potentials may be the most valuable indicator among the photopic electroretinogram parameters representing a quantitative measure of overall retinal dysfunction.
