白内障超声乳化手术后房角变化的年龄差异

摘要

目的：探讨白内障超声乳化手术（CUEA）前后前房角参数变化的年龄差异。方法CUEA患者174例（174只眼）分为A（＜60岁，36只眼）、B（60‐75岁，75只眼）和C（＞75岁，63只眼）三组，术前和术后1周、1个月、3个月和6个月以眼前节光学相干断层扫描（as‐OCT ）测量前房角相关参数，包括中央前房深度（ACD）、水平位和垂直位270度的前房角度（ACA）及其750μm处的前房角开放距离（AOD）和小梁虹膜空间面积（TISA）。结果 CUEA术后，ACD、ACA、AOD和 TISA均较术前增加（P＜0．05），B、C组增加的幅度较A组大（P＜0．05）。结论 CUEA术后，ACD、ACA、AOD和TISA均显著增大，老年患者的增加幅度更大。%Objective To explore the age difference of the changes in anterior chamber angle (ACA) in the patients after cataract ultrasonic emulsification operation(CUEA) .Methods A total of 174 patients(174 eyes) with cataract was assigned into three groups of A(<60 years old ,36 cases) ,B (60‐75 years old ,75 cases) and C (> 75 years old ,63 cases) .The ACA parameters of the anterior chamber depth (ACD ) ,ACD angle (ACAA ) ,anterior chamber angle opening distance (AOD ) and trabecular iris space area(TISA) at 270 degrees and 750 μm in horizontal and vertical levels were measured by anterior segment optical coherence tomography (as‐OCT ) before and in one week ,one month ,three months and 6 months after operation .Results Compared to before ,the ACD ,ACA ,AOD and TISA were all significantly increased after CUEA(P<0 .05) ,which were more in groups of B and C than those in group A(P<0 .05) .Conclusion The increases of ACD ,ACA ,AOD and TISA after CUEA are more in cataract patients aged greater than 60 years old than in the youngers with cataract .
