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。
Thirteen patients with cortical blind children were tested for visual evoked potentials using DANTECCANTATA1500 EMG / EPP. The result was VEP in all children with varying degrees of anomalies, flat waveforms, or reduced amplitude and latency. Of these, only 8 had VEPs documented, and their visual acuity recovered to varying degrees after treatment Cases of children did not record visual evoked potentials, visual acuity did not improve after treatment. The results suggest that visual evoked potential test, as an objective visual function test, can be used as an objective test to diagnose and prognose cortical blindness.
