The pattern visual evoked potential (PVEP) was analyzed in 22 patients (42 affected eyes) with retinitis pigmentosa, and in 9 cases the pattern electroretinogram (PERG) was simultaneously examined to find that (1) PVEP could be recorded in 31 (73.8%) and was normal in 17 (40.5%) of the affected eyes; (2) PVEP was related to visual acuity, being abnormal in all the eyes with visual acuity below 0.2, but normal in most eyes with visual acuity over 0.2; (3) the changes in PERG and PVEP were mostly consistent; and (4) PVEP and PERG might well be utilized for the morbid evaluation of central retina in patients with retinitis pigmentosa.
对22例视网膜色素变性患者（42只患眼）进行了图形视觉诱发电位（PVEP）分析，其中9例同时检查了图形视网膜电图（PERG），发现：（1）31只（73.8%）患眼可记录到PVEP，其中17只（40.5%）正常；（2）PVEP与视力有关，视力低于0.2的患眼PVEP均异常，而视力高于0.2的患眼多数PVEP正常；（3）PERG和PVEP的变化大多一致；（4）PVEP和PERG很可能可用于视网膜色素变性患者中心视网膜的病变评估。
