Oscillatory potentials of the electroretinogram in hypertensive patients with different antihypertensive treatment.
Oscillatory potentials of the electroretinogram are useful to confirm the diagnosis of essential hypertension. Thirty-five hypertensive patients underwent primary antihypertensive therapy with four different treatments. Oscillatory potentials were recorded before the treatment and after 12 months. The oscillatory response increased in a statistically significant manner in the angiotensin-converting enzyme inhibitor group. This is probably caused by the vasodilatation mechanism, which increases the retinal blood flow.
