Ocular mydriatics are diagnostic agents that generally facilitate a preferable ophthalmoscopic examination. However, the optometrist should be aware of certain iatrogenic side effects including the precipitation of an acute angle-closure. The purpose of this paper is to summarize the mechanism of mydriatic angle-closure glaucoma. In addition, a shallow anterior chamber is a fundamental ocular variable which should be evaluated before inducing mydriasis and/or cycloplegia. The technical procedures for the oblique illumination shadow test and the van Herick slit lamp test are presented, both of which provide an accurate estimation of the anterior chamber angle. The risk of precipitating an attack after reasonable circumspection by such evaluations approaches zero. However, should an attack occur, the procedures to rapidly lower the intraocular pressure and open the chamber angle are discussed.
眼科散瞳剂是一般有助于进行更理想的检眼镜检查的诊断剂。然而，验光师应意识到某些医源性副作用，包括急性闭角型青光眼的诱发。本文旨在总结散瞳性闭角型青光眼的发病机制。此外，浅前房是一个基本的眼部变量，在散瞳和/或睫状肌麻痹之前应进行评估。本文介绍了间接照明阴影试验和范·赫里克裂隙灯试验的技术操作，这两种方法都能准确评估前房角。通过这些评估进行合理谨慎操作后诱发发作的风险接近于零。然而，如果发作发生，本文将讨论迅速降低眼压和开放房角的操作。
