成熟期或膨胀期白内障可促发急性闭角型青光眼,即所谓晶体形态性青光眼,这种情况既可发生于房角关闭者,也可发生于开角者。若患眼为窄角或闭角,则晶体形态性青光眼只是急性闭角型青光眼的加速形式。而真正的晶体形态性青光眼发生于宽房角,只是由于白内障过于膨胀而致房角关闭,最初为瞳孔阻滞,以后表现为周边虹膜前移贴靠房角。晶体形态性青光眼多发生于发展中国家,因为在这些国家白内障成熟后才做手术,所以病人常常等到视力很差即白内障晚期才到医院就诊。由于晶体形态性青光眼房角关闭的始发机制为瞳孔阻滞,所以其治疗方法与原发性急性闭角型青光眼相同。即在药物降压后,应用缩 Mature or intumescent cataract can cause acute angle-closure glaucoma, the so-called crystal-shaped glaucoma, this situation may occur in the corner off, can also occur in the open-angle. If the affected area is narrow or closed, crystalline morphologic glaucoma is only an accelerated form of acute angle-closure glaucoma. The real crystal morphology of glaucoma occurs in the wide angle, but due to excessive expansion of the cataracts caused by angle closure, initially for the pupil block, after the performance of the peripheral iris forward by the angle. Crystallographic glaucoma occurs mostly in developing countries, because surgery in these countries after cataract maturation, so patients often wait until the poor vision to the hospital after cataract. Because of the mechanism of onset of closure of the crystalline morphologic glaucoma, pupillary block, so the treatment of primary acute angle-closure glaucoma and the same. That is, after the drug is depressurized, the application is reduced
