高褶虹膜型闭角性青光眼(Plateau Iris Angle-Closure Glaucoma 以后简称高虹闭青)被认为是原发闭青中无瞳孔阻滞的少见类型。根据文献,其主要临床特点有三:(一)瞳孔阻滞闭青的虹膜向前膨隆,中央和周边部前房均浅(图一),而高虹闭青之虹膜平坦,前房中央深度正常,周边部虹膜组织较厚,有褶、隆起。虹膜根部附于睫状体之角度较急陡,附着点也可偏前,故使房角入口极窄(图二)。在瞳孔扩大时,周边高褶虹膜极易将房角关闭。高虹闭青患者暗室试验阳性率颇高,且多患强阳性。扩瞳则常 High-fold iris-type closed-angle glaucoma (Plateau Iris Angle-Closure Glaucoma hereinafter referred to as high rainbow cypress) is considered a rare type of primary closed pupilless block. According to the literature, its main clinical features are three: (a) pupillary block closed the iris bulging forward, the central and peripheral anterior chamber are shallow (Figure I), and high rainbow green iris flat, central anterior chamber depth normal The peripheral iris tissue thicker, pleated, uplift. The root of the iris attached to the ciliary body angle is steep, the attachment point can also be partial, so the corner of the entrance very narrow (Figure 2). In the pupil to expand, the surrounding high iris can easily turn off the corner. High rainbow closed patients with dark room test positive rate is high, and more than strong positive. Dilatation is often
