2018-11-07 zyx整理 神经科病例撷英拾粹

55岁女性,注意到其右侧瞳孔形状奇特,伴有轻度疼痛。患者传入视觉检查,眼球和眼睑活动以及眼底都是正常的。

55岁女性,注意到其右侧瞳孔形状奇特,伴有轻度疼痛。患者传入视觉检查,眼球和眼睑活动以及眼底都是正常的。患者左侧瞳孔圆形,反射存在(图1)。 右侧瞳孔拉长(指向11:00和5:00)并强直(图2)。无眼压高或角膜水肿。一年后,瞳孔形状变为三角形;检查提示眼压高不伴有角膜水肿,证实为虹膜角膜内皮(ICE)综合征。本例是猫眼Adie样瞳孔的不寻常表现,为ICE综合征的先兆。

Adie瞳孔是一种良性强直性瞳孔,通常与虹膜括约肌的扇形麻痹有关。ICE综合征常伴有虹膜萎缩,青光眼和角膜水肿;本例有上述3个表现中的2个。Adie样瞳孔异常形状可提示ICE综合征。有必要转诊给眼科医生。

(图2:虹膜在12点到4点以及6点到10点直接出现扇形瘫痪,伴颞侧虹膜瞳孔边缘轻度变薄,形成类似Adie样瞳孔)
