同时记录的27例PERG和PVEP显示;视网膜病变主要表现为b波减低,P_(100)正常或b波和P_(100)潜伏期均延长,RCT正常;急性视神经炎的特点是b波正常,P_(100)潜伏期和RCT延长;视神经萎缩多表现为b波和P_(100)消失。提示PERG与PVEP联合应用较单项检查更有助于病变的定位。对视网膜和视神经病变的诊断与鉴别诊断有实用价值。
27 cases of PERG and PVEP were recorded at the same time. The main manifestations of retinopathy were b-wave reduction, normal P_ (100) or prolonged b-wave and P_ (100) latency, and normal RCT. Acute optic neuritis was characterized by normal b wave and P_ (100) Latency and RCT prolongation; optic atrophy mostly manifested as b-wave and P_ (100) disappearance. Tip PERG and PVEP combined application of more than a single check is more conducive to the localization of the lesion. Of retinal and optic neuropathy diagnosis and differential diagnosis of practical value.
