白内障囊内摘除术后,一旦发生瞳孔阻塞性青光眼,应用扩瞳治疗无效的病例,常需手术治疗。本文对于无晶体性瞳孔阻塞性青光眼手术给予简要的指导。诊断和手术适应症:当前房消失,眼内压超过正常,瞳孔阻塞的诊断是容易的。但当眼内压正常或低于正常,瞳孔阻塞常难于诊断。如果连续数天扩瞳,有效地加深了前房,而后又恢复到原样,那么即使眼内压正常或低下,还是存在瞳孔阻塞。此外对于所有低眼压的病例,都应检查眼底有无脉络膜脱离。应试用各种常用的散瞳剂和睫状肌麻痹剂扩大瞳孔,解除瞳孔阻塞。Tropicamide(1%my-
After cataract extraction, in the event of pupil obstructive glaucoma, the application of mydriasis treatment ineffective cases, often require surgery. This article gives a brief guide to aphakic pupil-blocking glaucoma surgery. Diagnosis and surgical indications: The current room disappears, intraocular pressure than normal, the diagnosis of pupillary obstruction is easy. However, when the intraocular pressure is normal or below normal, pupillary obstruction is often difficult to diagnose. If the pupil dilated for several days, effectively deepening the anterior chamber, and then returned to its original state, then even if the intraocular pressure normal or low, there is still clogged pupils. In addition, for all cases of low intraocular pressure, should check the presence or absence of choroidal detachment. Should try a variety of commonly used mydriatic and cycloplegic agents to expand the pupil, lift the pupil obstruction. Tropicamide (1% my-
