The angle closure glaucomas are defined by iridotrabecular contact, trabecular dysfunction, and elevated intraocular pressure (IOP). Laser iridotomy successfully eliminates the relative pupillary block component of the angle closure process, regardless of whether the underlying angle closure is related primarily to pupillary block or another mechanism. For those eyes with angle closure originating at an anatomic level posterior to the iris, such as plateau iris, lens-induced angle closure, or posterior segment processes, argon laser peripheral iridoplasty is often useful to further open the angle. The purpose of this article is to review the indications and techniques for laser iridotomy and laser iridoplasty in clinical practice.
闭角型青光眼是由虹膜小梁接触、小梁功能障碍和眼压升高所定义的。激光虹膜切开术成功消除了闭角过程中的相对瞳孔阻滞成分，无论潜在的闭角主要是与瞳孔阻滞还是其他机制相关。对于那些闭角起源于虹膜后方解剖层面的眼睛，如高褶虹膜、晶状体诱导的闭角或后段病变，氩激光周边虹膜成形术通常有助于进一步开放房角。本文的目的是回顾临床实践中激光虹膜切开术和激光虹膜成形术的适应证及技术。
