摘要 目的:通过观察埃迪瞳孔患者暗环境下双眼瞳孔大小及光反射情况,以对其病理生理改变进行更深入的了解。方法:用红外瞳孔测试仪对25例埃迪瞳孔患者双眼暗环境下瞳孔大小及光反射情况进行分析。结果与结论:埃迪瞳孔与对侧眼暗视下瞳孔大小相等(P>0.05),均小于正常人(P<0.05);对侧眼瞳孔直接、间接光反射曲线呈勺形,光刺激前呈现细小、规律、变换频率低的锯齿波,光刺激后迅速收缩,稳定1、2 s后渐平坦,偶见小幅度正弦波;埃迪瞳孔全程均呈现幅度不等、变换频率较快的不规则锯齿波,光刺激后无明显收缩;埃迪瞳孔的不对称性较对侧眼大(P<0.05);对侧眼瞳孔直接、间接光反射潜伏期与正常人相近(P>0.05),反应幅度较正常人略低(P<0.05)。应用红外瞳孔测试仪可对埃迪瞳孔及对侧眼瞳孔活动情况进行更深入、细致的观察。
