Latency-shift of intra-operative visual evoked potential predicts reversible homonymous hemianopia after intra-ventricular meningioma surgery

Clinical Neurophysiology Practice, 2019
Objectives: Intraoperative visual evoked potentials (VEPs) are used to monitor the function of optic radiation during neurosurgery with the P100 amplitude decrement as a predictor of post-operative visual deficit.

Diagnostic Criteria of Pattern VEP in Adult Monocular Amblyopic Patients

, 2013
성인 단안 약시 환자의 문양시유발전위 검사 결과를 정상 대조군과 비교하여 약시 진단에서의 기준을 제시해보고자 하였다. 2000년 1월부터 2011년 12월까지 병사용 진단서 발급을 위해 내원한 성인 약시 환자군과 정상군의 문양시유발전위 검사의 변수(Parameters), 즉 P100 잠복기, P100 진폭, P100 잠복기 및 진폭 비, P100 잠복기 및 진폭의 양안 차이를 후향적으로 분석하였다. 단안 약시군은 47명, 정상 대조군은 39명이었다.
