可疑原发性房角关闭患者双眼IOL Master参数对称性分析

Analysis of interocular symmetry of primary angle-closure suspects by IOL Master

目的:应用IOL Master观察可疑原发性房角关闭(primary angle closure suspect,PACS)患者的双眼对称性。方法:横断面观察性研究。纳入可疑PACS患者56例112眼,测量双眼眼轴长度(axial length,AL)、前房深度(anterior chamber depth,ACD)、角膜白到白距离(white to white,WTW Distance),并比较其差异;分析左右眼差值(△AL、△ACD和△WTW)与年龄、性别的相关性。结果:配对样本t检验结果显示,左右眼AL、ACD、WTW的差异均无统计学意义(P>0.05)。△AL、△ACD和△WTW与年龄、性别无明显相关性。结论:PACS患者ACD、WTW、AL具有双眼对称性,且该对称性不随年龄、性别而改变。

AIM： To observe the interocular symmetry of primary angle-closure suspects＇ （PACS） parameters using IOL Master. ~ METHODS： A cross- sectional observational study. Totally 112 eyes from 56 subjects were enrolled to detect the difference of the bilateral axial length （AL）, anterior chamber depth （ACD） and white to white distance （WTW）, and to evaluate the correlation between the interocular differences of AAL, AACD and AWTW and age, gender. RESULTS. All the parameters were analyzed by paired- samples t test and there were no significant interocular difference （P〉0.05）. There was no relation of △AL,△ACD and Avv-r3N with age and gender. CONCLUSION, Interocular symmetry of parameters by IOL Master was observed in PACS, and we found that the symmetry would not be altered when the age and gender had changed.
