目的应用频域眼前段光学相干断层扫描(OCT)分析周边虹膜切除术前后前房角的变化.方法原发性前房角关闭者32例(40只眼)行周边虹膜切除术,术前、术后2d、2个月使用频域眼前段OCT进行前房角测量,比较500 μm/750 μm前房角角度(ACA500/ACA750)和500 μm/750μm前房角开放距离(AOD500/AOD750)等指标.结果各指标在术前、术后差异有统计学意义,术后2d、2个月相应指标差异无统计学意义.结论原发性前房角关闭行周边虹膜切除术后前房角增宽,可缓解瞳孔阻滞,预防前房角进一步关闭,频域眼前段OCT可进行术前术后的非接触检查,实现前房的生物统计学测量.

Objective To evaluate the change of the anterior chamber angle before and after iridectomy by spectral domain-anterior segment optical coherence tomography(SD-AS OCT).Methods The clinical trial was carried out in 40 eyes of 32 cases with primary angle closure(PAC).500μm/750μm anterior chamber angle (ACA500/ACA750) and 500μm/750μm angle opening distance (AOD500/AOD750) were imaged with SD-AS OCT before and after iridectomy.Results There were statistical significant differences between preoperation and post-operation in ACAS00/ACA750 and AODS00/AOD750.No significant differences of above indexes were found between 2 days and 2 months after surgery.Conclusion The anterior chamber angle becomes wider in PAC patient after iridectomy.This improvement can relieve pupil block and prevent further chamber angle closure.SD-AS OCT can be used to carry out a noncontact biometrical measurement of anterior chamber before and after surgery.
