[Electrophysiologic signs of macular diseases].

In the past two years, we have treated 80 patients at our clinic for regional changes in the macula lutea. The results of the electrophysiological investigations carried out on these patients are reported: scotopic and photopic whole-field electroretinography (ERG), pattern ERG, and analysis of the visual flash- and pattern-evoked potentials. These different tests are suitable for assessing various types of pathological retinal function. Electrophysiological methods are appropriate for evaluating the degree and progression of the disease. In certain hereditary diseases of the retina, such as in Stargardt macular degeneration and in a few early cases of sex-related retinoschisis, electrophysiological data can also be valuable in making a differential diagnosis.
