Twenty-two patients with acute optic neuritis were studied by the techniques of infrared pupillometry and visual evoked responses (VER) to pattern reversal. A relative afferent pupillary defect was found in all cases and the magnitude of this defect was found to be related to the amplitude, but not to the latency, of the VER. During follow-up the afferent defect was found to remain persistently abnormal while other methods of clinical evaluation could not demonstrate abnormality reliably. The amplitude of the VER also remained low.
采用红外瞳孔测量技术和图形翻转视觉诱发电位(VER)技术对22例急性视神经炎患者进行了研究。所有病例均发现有相对性传入性瞳孔障碍,且该障碍的程度与VER的波幅有关,而与潜伏期无关。在随访期间,发现传入性障碍持续异常,而其他临床评估方法无法可靠地显示异常。VER的波幅也仍然较低。
