目的：观察光学相干断层成像（ optical coherence tomography，OCT）在眼科体检中对视网膜黄斑部疾病检出的应用价值。方法收集在某院健康体检中，自愿应用OCT在眼视网膜黄斑部检查者8302人，其中男5216人，女3086人，年龄23～72岁。视力0.05～1．5。分析OCT在体检人群眼黄斑部病变的早期筛查的作用。结果 OCT体检8302人，检出视网膜黄斑部病变1743人，检出率21．0％。视力0.05～0.3890人，检出880人，检出率98．9％；0.4～0.82153人，检出686人，检出率31.9％；＞0.85259人，检出177人，检出率3．4％。20～39岁1586人，检出105人，检出率6．6％；40～60岁5552人，检出926人，检出率16．7％；＞60岁1164人，检出712人，检出率61．2％。结论应用OCT对眼底黄斑部检查，其病变的检出率高，并与受检者年龄和视力呈一定的关系。在健康体检中能早期发现眼底黄斑部病变，是防盲治盲中不可缺少检测手段。%Objective To study the significance of optical coherence tomography OCT in retinal macule examination.Meth-ods Collecting data from people who were willing to have OCT examination in retinal macula, during their health examination in the hospital.Results Among 8302 volunteers, 5216 were male, 3086 were female.The age was from 23 to 72.Vison acuity ranged from 0.05-1.5.Analysing the significance of OCT in early period screening, 8302 volunteers were examined, 1743 of whom were diag-nosed of macular diseases.The positive rate was 21.0%.Vision acuity ranges from 0.05 to 0.3, 890 were examined and the positive rate was 98.9%(880).0.4-0.8, 2153 were examined and the positive rate was 31.9%(686);0.8, 5259 were examined and the positive rate was 3.4%(177).Among 1586 volunteers whose age range from 20 to 39, the positive rate was 6.6%(105).Among 5552 volunteers whose age were from 40 to 60, the positive rate was 16.7%(926).1164 volunteers were at 60, whose positive rate was 61.2%(712).Conclusion OCT has significant effect on examining retinal macular diseases, the positive rate is proportional to age and conversely proportional to vision acuity.It is helpful for diagnosing macular diseases timely in health examination, which plays a vital role in preventing blindness.
