Abstract

Background and objective: Diabetic macular edema has several patterns on optical coherence tomography. This retrospective study aimed to assess which retinal layers show thickness changes in type 1 diffuse diabetic macular edema with preserved vision.

Patients and methods: Eleven eyes with diffuse diabetic macular edema on optical coherence tomography and eight control eyes with 20/20 best-corrected visual acuity were enrolled. Optical coherence tomography images were segmented using an algorithm of the authors' design (OCTRIMA): regional thickness data in the central area, pericentral rings, and peripheral rings were obtained for the retinal cellular layers.

Results: The retinal nerve fiber layer showed no changes, the ganglion cell and inner plexiform composite layer and the ganglion cell complex were thicker only in the pericentral regions, and all other layers were thicker in all regions in diffuse diabetic macular edema. Macular thickness was normal in the peripheral region.

Conclusion: The results show that the outer retina in the foveal area is the most affected in diffuse diabetic macular edema.

光学相干断层扫描显示保留视力和弥漫性糖尿病黄斑水肿患者视网膜层厚度的变化。

背景与目的:糖尿病性黄斑水肿在光学相干断层扫描上表现为几种类型。本回顾性研究旨在评估1型弥漫性糖尿病黄斑水肿患者视网膜层的厚度变化。患者和方法:选取光学相干断层扫描显示的弥漫性糖尿病黄斑水肿患者11眼和最佳矫正视力为20/20的对照眼8眼。采用作者设计的光学相干断层成像算法(OCTRIMA)对图像进行分割，获得视网膜细胞层中央区域、中心周围环和外围环的区域厚度数据。结果:弥漫性糖尿病黄斑水肿视网膜神经纤维层未见改变，神经节细胞及内丛状复合层及神经节细胞复合物仅在中央周围区增厚，其余各层均在所有区域增厚。周边黄斑厚度正常。结论:糖尿病弥漫性黄斑水肿以外视网膜中央凹区为主要受累部位。
