摘　　要：目的探讨粘小管切开术与穿透性小梁切除术后黄斑中心凹厚度变化及其临床意义。方法前瞻性观察38例青光眼患者,其中17例(24只眼)进行粘小管切开术(A组)和21例(24只眼)进行穿透性小梁切除术(B组)。采用光学相干断层扫描(OCT3)测量其黄斑中心凹厚度。结果A组术后3d、1周、1个月眼压与术前比较均显著下降(P<0.01);术后3d、1周黄斑中心凹与术前比较厚度增加(P<0.01)。B组术后3d、1周、1个月眼压与术前比较均显著下降(P<0.01);术后3d、1周、1个月黄斑中心凹与术前比较厚度均增加(P<0.01)。结论粘小管切开术和穿透性小梁切除术均可有效控制眼压。粘小管切开术后短期的低眼压未造成黄斑视网膜厚度不可逆的改变,手术创伤较小,安全性高。Objective To compare retinal thickness of the macular fovea in patients undergoing viscocanlostomy or trabeculectomy at different follow-up times. Methods Of 38 glaucoma patients, 17 patients （24 eyes,group A） underwent viscocanlostomy and 21 （24 eyes,group B） trabeculectomy. Retinal thickness of the macular fovea was measured by optical coherence tomography （OCT3）. Results Compared with the baseline, intraoccular pressure （fOP） in group A was significantly decreased on the 3rd day, in 1 week and 1 month after operation （P〈0. 05）, and so did in group B （P〈0.05）. Foveal thickness in group A was elevated on the 3rd day and in 1 week after operation compared with the baseline （P〈0. 05）. In group B, foveal thickness on the 3rd day, in i week and 1 month after operation was elevated compared with the baseline （P〈 0. 05）. Conclusion Both of viscocanlostomy and trabeculectomy can control fOP effectively. Short term lowering of IOP after viscocanlostomy does not lead to an irreversible change of macular foveal thickness, and viscocanlostomy is a procedure with minimal injury and high safety.
