糖尿病性黄斑水肿的光学相干断层扫描与荧光血管造影图像的对比分析

目的对比分析糖尿病视网膜病变患者的光学相干断层扫描(optical coherence tomography,OCT)与荧光血管造影(fluorescein angiographic,FA)图像。方法回顾性分析不同阶段糖尿病视网膜病变70例患者95眼的OCT和FA图像。结果OCT图像显示视网膜水肿占70.5%,囊样黄斑水肿(cystoid macular edema,CME)占13.7%,浆液性黄斑脱离并发水肿占4.2%,浆液性黄斑脱离并发水肿和CME占2.1%,正常黄斑结构占9.5%。结论OCT为糖尿病视网膜病变黄斑结构的变化提供了依据,特别是对FA未能发现的早期黄斑结构改变的诊断具有重要意义。

A comparison of optical coherence tomographic(OCT) features with clinical and fluorescein angiographic findings in patients with diabetic retinopathy

Objective To compare optical coherence tomographic(OCT) features with clinical and fluorescein angiographic(FA) findings in patients with diabetic retinopathy.Methods A retrospective analysis was performed by reviewing ophthalmologic examinations together with FA and OCT images that had been obtained from 95 eyes of 70 patients at different stages of diabetic retinopathy. Results The OCT images showed retinal swelling in 70.5% of the eyes,cystoid macular edema(CME) in 13.7% of the eyes,serous foveal detachment swelling in 4.2% of the eyes,serous foveal detachment swelling CME in 2.1% of the eyes and normal foveal structure in 9.5% of the eyes. Conclusion OCT provided objective documentation of the structural changes in the fovea of eyes with diabetic retinopathy,which is especially important in the early stages of diabetic maculopathy when the structural changes are not yet evident angiographically.
