相干光断层扫描术对白内障超声乳化摘除联合人工晶状体植入术后低视力的临床观察研究

Clinical evaluation of low vision in age-related cataract eyes after phacoemulsification using OCT

目的运用相干光断层扫描术(OCT)研究无手术并发症的白内障患者在行白内障超声乳化摘除联合人工晶状体植入术后低视力的临床情况。方法前瞻性临床研究。共连续纳入2014年4月至2016年4月于上海市静安区市北医院白内障超声乳化摘除联合人工晶状体植入术,术中未发生手术并发症,术后1个月的最佳矫正视力<0.3的患者72例(72只眼),于术后1个月进行随访,记录最佳矫正视力(BCVA),并于术后1个月行OCT检查。结果入选患者的平均年龄为78.2岁。患者术后1个月BCVA小于0.3者占5.1%。OCT检查提示,导致患者术后低视力的原因有高度近视性脉络膜视网膜病变、老年性黄斑变性、糖尿病性视网膜病变、黄斑水肿、黄斑前膜、视网膜劈裂症、黄斑孔、视网膜色素变性。Logistic回归模型提示患者年龄是照成术后1个月低视力的危险因素。结论在本研究中,术后1个月OCT检查有助于了解患者术后低视力的原发病。

Objective To evaluate low vision in age-related cataract eyes after phacoemulsification （ Phaco） using optical coherence tomography （ OCT）. Methods In this prospective study, we consecutively recruited 72 low vision un- derwent uncomplicated phaeoemulsifieation. Post-operative visits were performed at 1 month. Best corrective visual acuity （ BCVA） was measured and OCT was used to evaluate the fundus. Results The mean age was 78.2 years. The ratio of low vision 1 month post operation was 5.1%. The main finding of OCT evaluation were degenerative myopia, age-related macular degeneration, diabetic retinopathy, maeular oedema, epiretinal membrane, retinoschisis, maeular hole, retinitis pigmentosa. Logistic regression shows the age was risk factor to cause low vision after surgery. Conclusions In this study, OCT shows great advantage in evaluating retinal disease after Phaco surgeryo
