摘　　要：目的:参照频域光相干断层扫描(频域OCT)分析B超对诊断白内障患者黄斑病变的准确性,从而为预测白内障术后视功能提供理论依据。方法:通过B超来初步了解白内障患者的眼后段情况,如发现黄斑区回声有异常,可继续行频域OCT来进一步确诊。结果:术前进行B超检查怀疑有黄斑病变的白内障患者178例217眼,进一步行频域OCT扫描。有213眼确诊有黄斑病变,其中湿型年龄相关性黄斑变性(AMD)70眼,黄斑前膜65眼,黄斑裂孔21眼,干型AMD 17眼,其他黄斑病变23眼,4眼频域OCT扫描显示为非黄斑区的后极部的其他病变。OCT完全扫描不到眼底的17眼,此17眼在行白内障手术后进行频域OCT检查均确诊为黄斑病变。结论:多数白内障患者无法看清眼底,B超就成为了解眼球后段的重要检查手段。因B超操作简单价格低廉,检查范围广,对患者的配合程度要求较低,且不受屈光间质混浊的影响,所以普遍作为白内障术前的常规检查之一。当B超显示怀疑有黄斑病变时再进一步行频域OCT扫描,二者的诊断相符性极高。AIM： To analyze the accurate diagnosis of macular diseases by B-scan ultrasound with the help of SD-OCT which can provide the theory basis for prediction of visual function of postoperative cataract surgery. METHODS：Posterior segment lesion of cataract patients can be primarily understood by B-scan ultrasound.OCT can be performed to further diagnose if there is abnormal echo in macular area. RESULTS： A total of 178 cataract patients （ 217 eyes ） who were suspected as macular diseases were examined by B-scan ultrasound and were scanned by OCT.A total of 213 eyes were diagnosed as maculopathy, including 70 eyes with wet age-related macular degeneration （ AMD） , 65 eyes with macular epiretinal membrane, 21 eyes with macular hole, 17 eyes with dry AMD and other 23 eyes with macular diseases.Results of frequency domain in 4 eyes showed that there were other lesions in the posterior pole in non-macular area.The fundus of 17 eyes can＇t be seen by OCT scan. These 17 eyes were diagnosed as maculopathy by SD -OCT of frequency domain after cataract operation. CONCLUSION： B-scan ultrasound can be important detection tool to understand the posterior segment lesion since most cataract patients＇ocular fundus are not clear. As B type ultrasound operation is simple, inexpensive and widely used for examination with a low degree of patients＇cooperation and no influences from opacity of optical media, it is often used as routine examine method before cataract surgery.If B-scan ultrasound examination shows signs of macular diseases, SD-OCT will be taken.The results of these two methods are quite constant.
