目的探讨B超检查对于成熟期白内障术前眼底病变的阳性诊断率,从形态结构方面协助术后视功能恢复的评估。方法收集2008年1月-2012年3月在新疆维吾尔自治区人民医院行因成熟期白内障行手术,并术后明确眼底病变的患眼120例,术前行眼科B超检查形态改变特征与术后眼底OCT及FFA检查结果相比较。结果 120眼中超声确诊玻璃体疾病及视网膜脱离符合率达100%;对于后部葡萄膜炎病变诊断符合率为85.7%,黄斑区病变诊断符合率96.4%,总阳性符合率95.8%。结论 B超检查能在很大程度上反映明显形态学改变的眼底病变情况,并能为估计预后提供重要依据。
Objective To investigate the positive diagnostic value of B-ultrasound for preoperative ocular fundus lesions in mature cataract and to evaluate the recovery of visual function after morphological and structural changes. Methods From January 2008 to March 2012 in the People’s Hospital of Xinjiang Uygur Autonomous Region due to mature cataract surgery and 120 cases of clear eyeground lesions, preoperative ophthalmic B-ultrasound examination of morphological changes and postoperative Fundus OCT and FFA test results compared. Results The coincidence rate of vitreous diseases and retinal detachment in 100 eyes was 100%. The coincidence rate of posterior uveitis was 85.7%. The coincidence rate of macular lesions was 96.4%. The total positive coincidence rate was 95.8%. Conclusion B-ultrasound can largely reflect the significant morphological changes of fundus lesions, and can provide an important basis for the estimation of prognosis.
