Abstract: The optical coherence tomography (OCT) combined with B-ultrasound were applied in the examination of fundus diseases in patients with cataract in this study. 220 patients (326 eyes) with cataract were given routine examinations such as intraocular pressure, visual acuity and slit lamp, as long as B-ultrasound and OCT examination. The detection of fundus diseases with different examination methods was compared. The results show that, 59 eyes of fundus diseases were detected by OCT, the detection rate was 18.10%; 23 eyes of fundus diseases were detected by B-ultrasound, the detection rate was 7.06%; 66 eyes of fundus diseases were detected by OCT combined with B ultrasound, the detection rate was 20.25%. Retinal cyst and retinal detachment were detected by B-ultrasound, which was OCT did not find and failed to diagnose. OCT also detected macular epiretinal membrane, macular hole,macular edema, central serous chorioretinopathy, vitreous macular traction, which were hard for 892 B-ultrasound to detected. The detection rate of OCT combined with B-ultrasound was significantly higher than that of the OCT or B-ultrasound alone. In a word, OCT combined with B-ultrasound can improve the diagnostic efficacy for fundus diseases and predict the recovery of postoperative vision.
