摘要
目的应用光学相干断层扫描（OCT）技术检测单纯年龄相关性白内障超声乳化并人工晶状体植入手术前后黄斑区视网膜厚度。方法对行超声乳化吸出术，且术前无合并症、术中无并发症的单纯年龄相关性白内障86例（104只眼）于术前及术后1周、1个月、3个月分别以OCT观察黄斑中心凹及黄斑区视网膜平均厚度的变化情况。结果所有术眼术后最佳矫正视力0．3～1．0，均较术前提高，OCT检查结果显示与术前比较术后1周黄斑中心凹厚度无增加，差异无统计学意义（t=-1．554，P=0．122），而黄斑区视网膜厚度增加，差异有统计学意义（t=-2．557，P=0．011）；手术后1个月黄斑中心凹厚度和黄斑区视网膜厚度与术前比较均有增加，差异有统计学意义（t=-3．975，P=0．000；t=-2．862，P=0．005）；术后3个月两区域厚度与术前比较差异均无统计学意义（t=-1．568，P=0．118；t=-0．197，P=0．844）。结论黄斑区视网膜平均厚度的检测可能比单纯黄斑中心凹厚度的检测更早、更全面地反映出患者白内障术后视网膜厚度增加的情况，为白内障术后黄斑水肿的诊治提供更多可靠依据。
Objective To study the thickness of foveal and macular retina before and after phacoemulsification and intraocular lens implantation of age-related cataract using optical coherence tomography （OCT）. Methods Retinal thickness of foveal and maeular sectors were measured using OCT in 104 eyes of 86 patients with age-related catract who underwent phacoemulsification. Data were collected at 1 day before the operation, and postoperatively at 1 week, 1 and 3 months. Results Postoperative best- corrected visual acuity （BCVA） were between 0. 3 to 1. 0 and improved in all eyes compared with preoperative BCVA. The OCT results showed that the difference was not statistically significant in fovea centralis thickness between preoperation and 1 week after operation （t = - 1. 554, P = 0. 122） , but the difference was statistically significant in thickness of macular area between the two time points （ t = - 2. 557, P =0.011 ）. There were statistically significant differences in the thickness of fovea centralis and maeular area between preoperation and 1 month after operation（ t = - 3.975, P = 0. 000 ; t = - 2. 862, P = 0. 005）. But between preoperation and 3 months after operation, the differences in the thickness of these two areas were not statistically significant （ t = - 1. 568, P = 0. 118 ; t = - 0. 197, P = 0. 844 ）. Conclusion The detecting of macular thickness using OCT may provide an earlier and more comprehensive description of the postoperative macular edema than the only detecting of the foveal thickness.
