OCT对糖尿病患者白内障超声乳化术后低视力原因的分析

目的:应用OCT对糖尿病患者白内障超声乳化吸除术后低视力的原因进行分析。 方法:对术后3d矫正视力低于0.5的50例50眼糖尿病患者行OCT检查,分析其结果。 结果:患者50眼中，黄斑水肿23眼,糖尿病眼底病变15眼，年龄相关性黄斑变性8眼, 黄斑板层裂孔2眼,2眼未发现异常。 结论:OCT作为一种新型的高分辨率的视网膜断层成像技术，对于糖尿病患者白内障术后造成低视力的原因的诊断具有指导作用，糖尿病白内障患者超声乳化吸除术后的黄斑水肿是影响术后低视力的主要原因之一。

Observation on the causes of the low vision in diabetic patients after phacoemulsification with optical coherence tomography

AIM: To observe the causes of the low vision in diabetic patients after phacoemulsification with optical coherence tomography (OCT) . METHODS: Fifty patients(50 eyes) with low vision after cataract operation were examined by OCT, and the causes of low vision were analyzed. RESULTS: In 50 eyes, 23 eyes had macular edema, 15 eyes with diabetic retinopathy, 8 eyes with senile macular degeneration, 2 eyes with macular hole, 2 eyes with normal OCT images. CONCLUSION: OCT is a new technique of retinal tomography with high-resolution.It is very valuable in the early diagnosis of the causes of low vision in diabetic patients after phacoemulsification. Macular edema is one of the most important causes of low vision in diabetic patients after phacoemulsification.
