比较高加索人和中国人激光周边虹膜切开术(LPI)前后眼前段的生物测量学参数。高加索人和中国人原发闭角型疑似病例的前瞻性临床队列研究。对LPI治疗前后的眼前节光学相干断层扫描图像进行分析，测量眼前节生物特征参数。种族间比较采用配对学生t检验。种族间比较采用单变量和线性混合效应回归模型。房角开放距离(AOD500，AOD750)；房角隐窝面积(ARA750)；虹膜厚度(IT750，IT2000，ITM)；虹膜曲率(ICURV)；前房面积(ACA)；前房体积(ACV)；前房宽度(ACW)。与中国人相比，高加索人术前ARA750、ACW和ICURV显著增加，而术前IT2000显著降低(P<；0.05)。术前AOD500、AOD750、IT750、ITCM、ACA和ACV的种族差异无统计学意义(P>；0.05)。两民族患者术后AOD500、AOD750、ARA750、ACA、ACV和ACW显著增加，ICURV显著降低(P<；0.05)。然而，LPI引起的AOD500、AOD750、ARA750、ACA、ACV、ACW和ICURV的变化量在两个种族之间没有差异(P>；0.05)。高加索人和中国人LPI术后均表现为房角宽度开放(AOD500、AOD750、ARA750)，前房内径扩大(ACA、ACV、ACW)，虹膜凸度变平(ICURV)。尽管高加索人术前眼前节解剖的某些方面在高加索人和中国人之间有所不同，但它们并没有转化为LPI引起的眼前节生物测量参数变化的显著种族差异。
To compare anterior segment biometric parameters between Caucasians and Chinese before and after laser peripheral iridotomy (LPI). Prospective clinical cohort study Caucasian and Chinese primary angle closure suspects. Anterior segment optical coherence tomography images captured before and after LPI were analyzed to measure anterior segment biometric parameters. Paired Student’s t-tests were used for within-ethnic group comparisons. Univariate and linear mixed-effects regression models were used for between-ethnic group comparisons. angle opening distance (AOD500, AOD750); angle recess area (ARA750); iris thickness (IT750, IT2000, ITM); iris curvature (ICURV); anterior chamber area (ACA); anterior chamber volume (ACV); and anterior chamber width (ACW). Caucasians had significantly greater preoperative ARA750, ACW, and ICURV and lower preoperative IT2000 compared to Chinese (P<0.05). Ethnic differences in preoperative AOD500, AOD750, IT750, ITCM, ACA, and ACV were insignificant (P>0.05). Significant postoperative increases in AOD500, AOD750, ARA750, ACA, ACV, and ACW along with significant postoperative decrease in ICURV were observed within both ethnic groups (P<0.05). However, the amount of LPI-induced changes in AOD500, AOD750, ARA750, ACA, ACV, ACW, and ICURV did not differ between the two ethnic groups (P>0.05). Both Caucasian and Chinese demonstrated opening of anterior chamber angle width (AOD500, AOD750, ARA750), expansion of anterior chamber dimensions (ACA, ACV, ACW), and flattening of iris convexity (ICURV) after LPI. Although certain aspects of anterior segment anatomy differed between Caucasians and Chinese preoperatively, they did not translate into significant ethnic differences in the amount of LPI-induced changes in the anterior segment biometric parameters.
