Abstract

To investigate the standing potential and its light rise in retinal detachments, a group of 33 patients was examined preoperatively. The group was divided into 3 subgroups according to the extent of the detachment. Apart from practical interest, this investigation was carried out to answer the question whether contact between the pigment epithelium and the receptor layer is necessary for the generation of the standing potential. This appeared not to be the case, on the contrary the standing potential was often higher. The EOG light rise, on the other hand, was more distributed in comparison with the extent of the detachment. Various features of the EOG may be explained, if we assume an inhibitory action of the retina on the generator of the standing potential under normal conditions.

摘要

为了研究视网膜脱离时的静止电位及其光反应上升，对33例患者进行了术前检查。根据脱离程度将该组患者分为3个亚组。除了实际意义外，进行这项研究是为了回答色素上皮与感受器层之间的接触对于静止电位的产生是否必要这一问题。情况似乎并非如此，相反，静止电位往往更高。另一方面，与脱离程度相比，眼电图光反应上升的分布更为分散。如果我们假设在正常情况下视网膜对静止电位发生器具有抑制作用，那么眼电图的各种特征就可以得到解释。
