Purpose: To study the classifications of qualitative characteristics on the angle configurations in the acute primary angle closure (APAC) and fellow eyes by ultrasound biomicroscopy (UBM).
Methods: A total of 131 patients (262 eyes) were researched retrospectively. The qualitative parameters from UBM images were classified into iris form (IF), ciliary body configuration (CBC), basal iris thickness (BIT), iris convexity (IC), iris insert (II), iris angulation (IA), ciliary body size (CBS) and ciliary body position (CBP). Comparative analyses between the APAC (case group) and fellow (control group) eyes were performed.
Results: There were significant differences in IF, CBC, IC, II, CBS, CBP between the case group and control group in all quadrants (P< 0.001). The IA of the case group and control group presented significant difference in all quadrants (P=0.001). However, there was not a significant difference in BIT between the case group and control group in all quadrants (P=0.495). The case group had fewer parallelogram-like and mushroom-like and more cone-like and hook-like CBCs than the control group (P< 0.001).
Conclusion: Multiple ciliary body configurations can influence the stability of the lens and the anatomic configuration of the anterior chamber angle indirectly. New qualitative classification system of UBM may be more intuitionistic and refined to reflect the angle configurations to help clinical practice.

通过超声生物显微镜对急性原发性闭角中角度构型的定性分类
目的：通过超声生物显微镜（UBM）研究急性原发性闭角（APAC）和对侧眼角构型的定性分类。
方法：对131例262眼患者进行回顾性研究。来自 UBM 图像的定性参数分为虹膜形式 (IF)、睫状体配置 (CBC)、基础虹膜厚度 (BIT)、虹膜凸度 (IC)、虹膜插入 (II)、虹膜角度 (IA)、睫状体大小(CBS) 和睫状体位置 (CBP)。进行了 APAC（病例组）和同伴（对照组）眼睛之间的比较分析。
结果：病例组与对照组各象限IF、CBC、IC、II、CBS、CBP均存在显着差异（P< 0.001)。病例组和对照组的IA在所有象限中均存在显着差异（P =0.001）。但病例组与对照组各象限BIT均无显着差异（P =0.495）。与对照组相比，病例组平行四边形和蘑菇状CBCs较少，圆锥状和钩状CBCs较多（P < 0.001）。
结论：多种睫状体构型可间接影响晶状体的稳定性和前房角的解剖构型。UBM新的定性分类系统可能更加直观和精细，以反映角度配置以帮助临床实践。
