Electroretinography (ERG) has been utilized to claim that the various hereditary subtypes of retinitis pigmentosa (RP) could be distinguished according to the temporal characteristics of the b wave. This study compares two different ERG techniques, one utilizing constant amplitude response and the other balanced photopic and scotopic stimuli, for the early diagnosis of RP. Both methods were found to be reliable objective tests for diagnosing RP. Neither test could differentiate between dominant, autosomal recessive, or X-linked RP.
视网膜电图（ERG）已被用于宣称，视网膜色素变性（RP）的各种遗传性亚型可根据b波的时间特征加以区分。本研究比较了两种不同的ERG技术，一种采用恒定振幅反应，另一种采用明视和暗视刺激平衡法，用于RP的早期诊断。结果发现，这两种方法都是诊断RP的可靠客观测试。两种测试均无法区分显性、常染色体隐性或X连锁RP。
