摘要
对51例96只慢性青光眼和51例102只正常眼进行了视诱发电位试验,发现青光眼组的VEP波幅(amplitude)较正常组显著降低(P<0.001),青光眼的VEP潜伏期(Latency)和波幅与垂直杯盘比(C/D)的大小有关,显示VEP对慢性青光眼的早期诊断有一定价值。
The visual-evoked potentials (VEP) of 102 normal eyes (51 cases) and 96 eyes (51 cases) with chronic glaucoma were determined. The study results showed that: 1) The amplitude of, VEP in chronic glaucoma (5.73±3.10uV) showed more lower than nomal persons(9.45±4.16uV). There is significant difference between them (P<0.001). 2) There is the correlation existing between VEP and vertical C/D ratio, so the value of VEP in diagnosis of chronic glaucoma is higher.
