Abstract

An electroretinographic (ERG) technique is described in which the relationship between scotopic b wave amplitude and stimulus light intensity is determined. The relative amplitude of scotopic to photopic responses is assessed by means of red light and flicker. The method is applied to the detection of ERG abnormalities in heterozygotes for X-linked retinitis pigmentosa. These have been found in only a proportion of cases. The ERG results can be used to suggest the nature of the retinal abnormality.

摘要

本文描述了一种视网膜电图(ERG)技术,该技术可确定暗视b波振幅与刺激光强度之间的关系。通过红光和闪烁光评估暗视与明视反应的相对振幅。该方法应用于检测X连锁视网膜色素变性杂合子的ERG异常。仅在部分病例中发现了这些异常。ERG结果可用于提示视网膜异常的性质。
