目的：探讨光学相干断层扫描( OCT )联合眼部B超对白内障患者术前眼底检查的临床价值。<br> 方法：通过常规检眼镜、眼部B超及OCT对176例278眼白内障患者术前进行眼底病检查,计算三种检查方法对眼底病的阳性检出率,并利用McNemar检验对数据进行配对分析,比较不同检查方法对眼底病诊断的价值。<br> 结果：常规检眼镜检出眼底病32眼(眼底病阳性率为11.5%),眼部B超检出眼底病18眼(6.5%),其中晶状体严重混浊患者有6眼(2.2%),OCT检出眼底病51眼(18.3%),OCT联合眼部B 超眼底病阳性病例为57眼(20.5%)。 OCT检出眼底病阳性率与B超、常规检眼镜及OCT联合眼部B超检出的眼底病阳性率在α=0.05水平均具有显著性差异。<br> 结论：三种检查方法比较OCT的价值较大,对黄斑区病变检查灵敏度高,但在患者晶状体严重混浊时,OCT无法获取眼底黄斑区视网膜结构,而眼部B超很好弥补OCT眼底检查的“盲区”,两者联合使用,对眼底病的准确诊断以及术后视力恢复预测价值最大。
目的：探討光學相榦斷層掃描( OCT )聯閤眼部B超對白內障患者術前眼底檢查的臨床價值。<br> 方法：通過常規檢眼鏡、眼部B超及OCT對176例278眼白內障患者術前進行眼底病檢查,計算三種檢查方法對眼底病的暘性檢齣率,併利用McNemar檢驗對數據進行配對分析,比較不同檢查方法對眼底病診斷的價值。<br> 結果：常規檢眼鏡檢齣眼底病32眼(眼底病暘性率為11.5%),眼部B超檢齣眼底病18眼(6.5%),其中晶狀體嚴重混濁患者有6眼(2.2%),OCT檢齣眼底病51眼(18.3%),OCT聯閤眼部B 超眼底病暘性病例為57眼(20.5%)。 OCT檢齣眼底病暘性率與B超、常規檢眼鏡及OCT聯閤眼部B超檢齣的眼底病暘性率在α=0.05水平均具有顯著性差異。<br> 結論：三種檢查方法比較OCT的價值較大,對黃斑區病變檢查靈敏度高,但在患者晶狀體嚴重混濁時,OCT無法穫取眼底黃斑區視網膜結構,而眼部B超很好瀰補OCT眼底檢查的“盲區”,兩者聯閤使用,對眼底病的準確診斷以及術後視力恢複預測價值最大。

AIM: To investigate the clinical value of optical coherence tomography ( OCT ) combined with ophthalmic B- type ultrasound in fundus examination before cataract surgeries. <br> METHODS:Conventional ophthalmoscope, ophthalmic B-type ultrasound and OCT were used to exam the fundus of 176 cataract patients (278 eyes). The positive rate of fundus diseases by the three methods was calculated, and then McNemar test was used to analyze the data in pairs and the values of the three methods on diagnosis of fundus diseases were investigated. <br> RESULTS:Thirty-two eyes were diagnosed with fundus diseases by conventional ophthalmoscope with positive rate of 11. 5%, 18 eyes ( 6. 5%) by ophthalmic B-type ultrasound, 6 eyes (2. 2%) of those 18 eyes were serious lens turbidity. Fifty-one eyes (18. 3%) were diagnosed with fundus diseases by OCT and 57 eyes ( 20. 5%) by OCT combined with ophthalmic B-type ultrasound. The positive rate of fundus disease detected by OCT had significant difference at the level of α= 0. 05 compared with those by ophthalmic B - type ultrasound, conventional ophthalmoscope and OCT combined with ophthalmic B-type ultrasound. <br> CONCLUSION: OCT is more valuable and more sensitive on detecting macular diseases than the other two. However, the structure of retinal layer of the patients who had serious lens turbidity cannot be observed, which can be remedied by ophthalmic B-type ultrasound. The examination of OCT combined with ophthalmic B-type ultrasound is the most valuable one on accurate and early diagnosis of fundus diseases and the prediction of the visual acuity after surgeries.
