白内障超声乳化手术后黄斑区光学相干断层扫描

目的:观察白内障超声乳化吸除联合人工晶状体植入术后黄斑中心凹厚度的改变。方法:对行白内障超声乳化吸除联合人工晶状体植入术,且术前、术中无并发症患者56例56眼,行术前及术后1,3mo黄斑区OCT检查,观察术眼黄斑中心凹厚度变化及视力变化。结果:56眼黄斑中心凹视网膜平均厚度术前为241.3±9.9μm,术后1mo为(260.7±16.8)μm,术后3mo为(245.6±17.6)μm,术后1mo与术前比较,差异有显著性意义(P=0.000),术后3mo与术前比较,差异无显著性意义(P=0.137)。术后1mo,2眼出现黄斑囊样水肿,术后3mo,1眼黄斑囊样水肿消退,另1眼黄斑囊样水肿较前略降低,其余眼未出现黄斑囊样水肿。结论:白内障超声乳化吸除联合人工晶状体植入术后1mo黄斑中心凹厚度明显增加,术后3mo大部分黄斑水肿消退。

Optical coherence tomography of macula area after cataract phacoemulsification

·AIM:To observe macula changes in patients after cataract phacoemulsification by optical coherence tomography(OCT).·METHODS:Fifty-six patients were included in this study.The uncomplicated phacoemulsification was performed.OCT was examined preoperatively,1 month and 3 months after surgery.Preoperative visual acuity,the retinal thickness were compared with those after surgery.·RESULTS:Preoperative and 1 month after surgery,the mean foveal thickness was(241.3±9.9)μm and(260.7±16.8)μm,with significant difference(P=0.000).The mean foveal thickness was(245.6±17.6)μm 3 months after surgery without significant difference compared with preoperative(P=0.137).two eyes displayed cystoid macular edema at 1 month after surgery and 1 eye of them was resolved 3 months after surgery.·CONCLUSION:The retinal thickening and macular edema can be found 1 month after uncomplicated cataract phacoemulsification.Three months Postoperatively,macular edema disappears and does not show significant difference compared with preoperative.·
