Studies on the Early Receptor Potential in the Human Eye VIII. ERP in Behçet’s Disease
Abstract
In 22 cases of Behçet’s disease (43 eyes, one eye with corneal staphyloma being excluded) manifesting ocular symptoms in the complete form, abnormal changes in the amplitude of the early receptor potential (ERP) were noted at the first consultation in 51.2% of the eyes examined as compared with 53.3% with abnormal areal indices (∑A) of the oscillatory potential and 39.5% with abnormal amplitudes of the b-wave in the ERG. Almost the same detection rate of abnormalities as in the ∑A of the oscillatory potential was obtained with respect to the ERP amplitude. The ERP and the b-wave were either reduced in their amplitude or absent in accordance with the grade and duration of this disease. Relatively early disappearance of the oscillatory potential was also noted.
As a result, it was concluded that the concomitant recordings of ERP and ERG are of high clinical value in evaluating the retinochoroidal function in this disorder.
