目的:观察图形视觉诱发电位与静态定量视野测量在青光眼诊断中的应用价值.方法:用图形视觉诱发电位和静态定量视野(Humphrey30-2)联合测量了16例(16眼)原发性开角型青光眼的视功能.结果:视觉诱发电位的异常率是69%;视野测量的异常率是75%.94%的受检眼有一项或两项检查项目异常.结论:当刺激图形空间频率较低(刺激方格较大)时,或者当受检眼视力较低时,视觉诱发电位和视野的异常率较高.图形视觉诱发电位与静态定量视野测量对青光眼的诊断具有很大的参考价值.
目的:觀察圖形視覺誘髮電位與靜態定量視野測量在青光眼診斷中的應用價值.方法:用圖形視覺誘髮電位和靜態定量視野(Humphrey30-2)聯閤測量瞭16例(16眼)原髮性開角型青光眼的視功能.結果:視覺誘髮電位的異常率是69%;視野測量的異常率是75%.94%的受檢眼有一項或兩項檢查項目異常.結論:噹刺激圖形空間頻率較低(刺激方格較大)時,或者噹受檢眼視力較低時,視覺誘髮電位和視野的異常率較高.圖形視覺誘髮電位與靜態定量視野測量對青光眼的診斷具有很大的參攷價值.

Sixteen cases(16 eyes)of primary open-angle glaucoma(POAG) were tested with pattern visual evoked potential(PVEP) and static quantitative perimetry(Humphrey30-2).In the POAG eyes,the rate of abnormal PVEP was 69% and it was 75% for perimetry.94% of eyes were abnormal in at least one of the tests.When the spatial frequency of the stimulating checkerboard was lower(the check size was larger),or the visual acuities were less than 1.0,the abnormal rate of PVEP and visual field were higher.
