摘　　要：使用ＤＡＮＴＥＣＣＡＮＴＡＴＡ１５００型肌电／诱发电位仪对１３例皮质盲幼儿进行视觉诱发电位检测。结果是所有患儿的ＶＥＰ均有不同程度的异常，波形平坦，或波幅降低和潜时延长；其中仅８例患儿可记录到ＶＥＰ，经治疗后他们的视力有不同程度的恢复；另５例患儿记录不到视觉诱发电位，经治疗后视力没有改善。结果提示：视觉诱发电位检测作为一种客观的视功能检查方法，对皮质盲的诊断和预后判定可作为一种客观的测试手段。13 infants who had cortical blindness were investigated with recording of visually evoked potentials (VEP) using Dantec Cantata 1500. All patients showed abnormal visual evoked responses including the latency delayed, the amplitude low and the waveform flat. After treatmeat 8 out of 13 cases recordabel VEP responses had some degree recovery in visual ability; however the others (5/13) without any VEP responses had no recovery. The results suggested that VEP might be used as an objective method for visual function evaluation in young children and might put a prognosis on the recovery of visual activity in infant with cortical blindness.
