摘　　要：目的探讨窄房角患者合并虹膜睫状体囊肿的解剖因素。方法回顾性病例系列研究。收集223例（402只眼）窄房角患者的超声活体显微镜（UBM）检查资料，进行回顾性分析。所有窄房角患者就诊时眼部常规检查均未发现虹膜睫状体囊肿体征，但眼部UBM检查显示有19例（23只眼）合并存在虹膜睫状体囊肿。根据UBM图像显示的囊肿部位、大小、数量，分析窄房角合并虹膜睫状体囊肿与未合并虹膜睫状体囊肿患者间年龄、中央前房深度、前房角等解剖特征差异。年龄、中央前房深度比较采用独立样本t检验，前房角比较采用独立样本秩和检验。结果223例（402只眼）窄房角患者中，UBM检查发现19例（23只眼）合并虹膜睫状体囊肿，UBM检测阳性率为5．7％。其中单眼囊肿15例，双眼囊肿4例；囊肿位于睫状突部2只眼（8．7％），虹膜根部18只眼（78．3％），同时位于虹膜根部及虹膜后表面3只眼（13．0％）；单发性囊肿21只眼（91．3％），多发性囊肿2只眼（8．7％）；囊肿直径0．5～3．1mm，平均（0．71±0．53）mm。窄房角合并虹膜睫状体囊肿患者平均年龄（55．32±10．74）岁，中央前房深度（2．25±0．39）mm；未合并虹膜睫状体囊肿患者年龄（57．46±10．52）岁，中央前房深度（2．14±0．34）mm，两者差异无统计学意义（t=0．534，0．783；P〉0．05）。合并虹膜睫状体囊肿患者前房角开放度中位数（最大值，最小值）为8．2°（21．0°，0．0°），未合并虹膜睫状体囊肿患者前房角开放度中位数（最大值，最小值）为8．9°（21．4°，0．0。°），两者差异无统计学意义（Z=-0．062，P〉0．05）。结论窄房角患者的中央前房深度及前房角开放度并非发生虹膜睫状体囊肿的解剖因素。Objective To investigate the prevalence and anatomy features of iridociliary body cysts in patients with narrow anterior chamber angle. Methods Retrospective case series study. The prevalence and anatomy features of iridociliarybody cysts in 223 patients （402 eyes） were analyzed retrospectively with ultrasound biomieroscopy （UBM）. All of the patients were examined for susceptive narrow anterior chamber angle without complaint. The age of the patients, the site, diameter and number of cysts, the anterior chamber angle and the central anterior chamber depth were measured. Results Iridociliary body cysts were found in 19 patients （23 eyes） out of 223 patients （402 eyes）, the prevalence is 5.7%. Fifteen patients were unilateral and four patients bilateral. Two cases originated from the ciliary process, eighteen cases from the iris root, and three from both the root and posterior surface of the iris. Twenty one cases were single cysts while two cases were multiple cysts. The diameter of the cysts ranged from 0. 5 to 3.1 mm, averaged （0. 71 ± 0. 53 ） mm. The average age and the central anterior chamber depth of the eyes with iridociliary body cysts were（55.32 ± 10. 74） years and（2. 25 ± 0. 39 ） ram, with no significant difference（ t = 0. 534,0. 783 ; P 〉 O. 05）as compared to that of patients without cysts, which were （57. 46 ± 10. 52）years and （2. 14 ± 0. 34）mm. The anterior chamber angle in iridociliary body cysts group was 8.2° （21.0° ,0. 0°）, with no significant difference（ Z = -0. 062 ,P 〉 0. 05 ）as compared to that of patients without cysts, which was 8.9°（21.4° ,0. 0° ）. Conclusions The prevalence rate of iridociliary body cysts in this study is 5.7% , central anterior chamber depth and anterior chamber angle in patients with cysts do not differ form patients without cysts.
