光学相干断层扫描在白内障术后低视力原因分析中的应用

目的 :探讨光学相干断层扫描图像在分析白内障术后低视力中的应用。方法 :对术后矫正视力低于 0 5的 48例 (4 8眼 )病人行OCT检查 ,分析其结果。结果 :48眼中黄斑水肿 2 1眼 ,老年性黄斑变性 8眼 ,糖尿病眼底病变 5眼 ,视网膜中央静脉栓塞 2眼 ,视神经萎缩 2眼 ,视网膜脱离 1眼 ,黄斑板层裂孔 2眼 ,7眼未发现异常。结论 :OCT是一种新的、非接触的诊断技术 ,在白内障术后低视力原因分中 ,它能快速准确地检查出低视力的原因 ,并能客观的检测临床治疗效果。

Etiological analysis of low vision after cataract operation with optical coherence tomography

Objective:To evaluated the application of optical coherence tomography (OCT) in the analysis on the causes of low vision after cataract operation. Methods:48 patients with low vision after cataract operation were examined by OCT,and the causes of low vision were analyzed. Results:In 48 cases,21 cases had macular edema,8 cases senile macular degeneration,6 cases diabetic retinopathy,2 cases obstruction of the central retinal vein,2 cases macular hole,l case retina detachment,7 cases had normal OCT images. Conclusions:OCT is potentially useful as a new noninvasive diagnostic technique for quantitative examination after cataract operation,the cause of low vision after cataract operation can be known by OCT fast and accurately,and the clinical course can be objectively monitored.
