相干光断层扫描对白内障患者术前眼底评估的意义

目的探讨相干光断层扫描（OCT）对白内障患者行术前眼底评估的优势。方法通过OCT对患者黄斑进行扫描,观察年龄相关性白内障患者术前黄斑区视网膜的显微结构。结果 127例（185只眼）白内障患者中,49例（52只眼,28.1%）患者由于晶状体混浊严重,用OCT仪无法进行扫描,107例（133只眼,71.9%）可通过OCT对黄斑区的细微结构进行大概评估。其中,80例（103只眼）OCT检查未见明显异常;术前OCT检查发现异常的有27例（30只眼）：硬性渗出1例（1只眼）,黄斑水肿8例（10只眼）,视网膜前膜2例（2只眼）,玻璃膜疣4例（5只眼）,色素上皮脱离4例（4只眼）,视网膜劈裂3例（3只眼）,视网膜出血3例（3只眼）,陈旧性脉络膜破裂1例（1只眼）,玻璃体黄斑牵拉1例（1只眼）。结论术前通过OCT检查,可了解黄斑区视网膜的细微结构,及早发现眼底病变,可对大多数白内障患者的眼底进行有效评估。

Fundus evaluation before cataract operation by optical coherence tomography

Objective To evaluted the advantages of fundus examination by optical coherence tomography(OCT) before cataract surgery.Methods We investigated retinal microstructure of macula in patients with age-related cataract by OCT.Results A total of 127 patients(185 eyes) were enrolled.Retina could not be examined by OCT in 49 patients(52 eyes,28.1%) because of severe opaque lens.In 107 patients(133 eyes,71.9%),OCT were used to evaluate the retina microstructure of macula.OCT indicated normal retina in 80 cases(103 ...
