[Changes in the oscillatory potentials in the electroretinogram during the evolution of diabetic retinopathy].
Oscillatory potentials where intensely studied in diabetic patients with various degrees of retinopathy. Classical reports pointed out the early reduction of their amplitude, as well as of their latency, while a and b waves remained still normal. A prognostic value was attached to these modifications, the reduction of oscillatory potentials being correlated with a ten time higher probability of developing a high risk retinopathy. 27 diabetic patients where investigated electroretinographically by us. No significant variation of the amplitude of oscillatory potentials was observed during the progression of diabetic retinopathy.
