抗青光眼手术后眼压仍高的原因甚多,应仔细分析鉴别。术后1-2天内暂时性的眼压升高,是由于短时间房水产生过多、蛋白含量增加以及相应的小梁阻滞所引起、不久即可自行下降。本文着重考虑的是正确的按照适应证和操作规程进行手术而未能达到预期的效果,现分为虹膜切除与滤过手术两类分述如下: 一、虹膜切除术后眼压升高有几种可能: 1.持续的急性原发性房角阻滞:周边虹膜切除仅切除了基质层而遗留下色素层,或切除孔太小被睫状突所堵塞,因而没有达到在房角范围内前后房交通的目的。这时应作第二个较大的穿通性的虹膜切除。某些病例也可不再做手术而用
Intraocular pressure is still high after anti-glaucoma surgery for many reasons, should be carefully analyzed to identify. Temporary intraocular pressure rise within 1-2 days after surgery is due to a brief episode of aqueous humor, increased protein levels, and consequent trabecular blockage, which can soon be reduced on their own. This article focuses on the correct operation in accordance with the indications and procedures failed to achieve the desired effect, is divided into two types of iris resection and filtration surgery are as follows: First, IOP after IOP increased a few Species may: 1. Persistent acute primary angle block: Peripheral iridotomy only excludes the stroma and left the pigment layer, or the excision hole is too small to be clogged by the ciliary process and thus does not reach the angle of the anterior chamber The purpose of traffic before and after the room. At this time should be the second larger penetrating iris resection. Some cases can no longer be used to surgery
