title: Proliferative retinopathy: value of the oscillatory potentials.
abstract: Oscillatory potentials (OPs) and retinal fluorescein angiography (RFA) were performed in 45 patients with diabetes mellitus. OPs were normal in 28 patients, altered (increased latencies and or inter-peak times) but with normal shape in 9, changes in morphology in 8: none of these patients had normal RFA, 2 had no proliferative retinopathy, 6 proliferative retinopathy (PR). In the authors' opinion OP changes in morphology are nearly always caused by a serious diabetic retinopathy, often by a PR. The authors emphasize the usefulness of OPs for studying the neurophysiologic properties of the retina of diabetic patients, particularly in PR.
