To compare the anterior segment optical coherence tomography (AS-OCT) measurements of eyes with pigment dispersion syndrome (PDS) and ocular hypertension (OHT) before and after neodymium:yttrium-aluminum-garnet (Nd:YAG) laser peripheral iridotomy (LPI).
A total of 23 eyes of 23 patients with PDS and OHT with features of PDS were included in this retrospective study. All of the eyes with PDS and OHT were examined by AS-OCT before and after Nd:YAG LPI. Anterior chamber depth, angle opening distance 500, angle opening distance 750, trabecular iris space 500, trabecular iris space 750 and scleral spur angle, iris bowing and iris shape were measured with AS-OCT by the same examiner.
The differences in all parameters before and after Nd:YAG LPI were statistically significant. Iris configuration was concave in all eyes prior to iridotomy. After Nd:YAG laser iridotomy, the iris configuration became convex in 7 eyes, flat in 9 eyes and remained concave in 7 eyes.
Nd:YAG laser peripheral iridotomy is an effective method for reversing the iris concavity and iris bowing in pigment dispersion syndrome.
比较钕：钇铝石榴石（Nd：YAG）激光周边虹膜切开术（LPI）前后色素性分散综合征（PDS）合并高眼压症（OHT）患者眼前节光学相干断层扫描（AS - OCT）的测量结果。
本回顾性研究纳入了23例患有PDS及具有PDS特征的OHT患者的23只眼。所有PDS合并OHT的眼睛在Nd：YAG LPI前后均接受了AS - OCT检查。由同一位检查者使用AS - OCT测量前房深度、500角开放距离、750角开放距离、500小梁虹膜间隙、750小梁虹膜间隙、巩膜突角、虹膜弯曲度和虹膜形态。
Nd：YAG LPI前后所有参数的差异均具有统计学意义。虹膜切开术前所有眼睛的虹膜形态均为凹形。Nd：YAG激光虹膜切开术后，7只眼的虹膜形态变为凸形，9只眼变为扁平形，7只眼仍为凹形。
Nd：YAG激光周边虹膜切开术是一种有效逆转色素性分散综合征中虹膜凹陷和虹膜弯曲的方法。
