激光周边虹膜切除术后前房及房角形态评价方法的研究进展

Evaluation methods of anterior chamber and angle structures after laser peripheral iridotomy

激光周边虹膜切除术（LPI）通过部分解除瞳孔阻滞，增宽周边前房角，降低眼压而成为青光眼治疗的重要手段之一。LPI术后前房角形态的检测参数是评价LPI治疗效果的主要指标。随着检测手段的进步，目前对LPI手术前后前房及房角形态的评价正在逐渐深入。已有的房角检查方法包括前房角镜、超声生物显微镜（UBM）、眼前节OCT（AS—OCT）以及Pentacam等，每种方法均可获得其各自的评价参数，但也存在一定限制。就LPI术后上述检查方法在评价前房及房角形态方面的应用价值进行总结，同时总结LPI术后前房和前房角结构的变化。

Laser peripheral iridotomy （LPI） is one of the main therapy for glaucoma due to its reliable efficacy of widening peripheral angle and therefore decreasing intraocular pressure by partially relieving pupillary block. The parameters of the anterior chamber angle following the LPI are the main evaluation indexes. At present, the detecting and diagnosis technique for the anterior chamber angle is deeply advancing ,including gonioscopy ,ultrasound biomicroscopy, anterior segment optical coherence tomography and Pentacam. These methods offer some useful parameters and also present with some limits in the application respectively in the evaluation of anterior chamber and angle structure. This review focuses on the application of Methods mentioned above and morphologic changes of anterior chamber and angle structure following the LPI.
