Abstract

Introduction: Macular edema (ME) is a leading cause of visual impairment associated with various retinal pathologies. Spectral-domain optical coherence tomography (SD-OCT) provides high-resolution imaging, allowing detailed assessment of ME patterns and structural changes.

Aim: The aim of this study was to evaluate the distribution and characteristics of ME across different etiologies using SD-OCT.

Materials and methods: This cross-sectional observational study included patients with ME from diverse etiologies. SD-OCT was used to assess central macular thickness, retinal volume, cystoid spaces (CS), epiretinal membrane (ERM), hyperreflective foci, and disorganization of retinal inner layers (DRIL).

Results: A total of 54% of the study participants were female, with a mean age of 57 years. Diabetes mellitus (50.4%) was the most common etiology, followed by retinal vein occlusions, age-related macular degeneration, ERM, and inflammatory causes. CS were observed in 49.6% of cases, and DRIL in 48%. Severe visual impairment was more frequent in diabetic and vaso-occlusive cases.

Conclusion: SD-OCT effectively identifies structural patterns in ME across etiologies, assisting in diagnosis and management planning.

黄斑水肿的光学相干断层扫描分析。

黄斑水肿（ME）是与各种视网膜病变相关的视力损害的主要原因。光谱域光学相干断层扫描（SD-OCT）提供高分辨率成像，允许详细评估ME模式和结构变化。目的：本研究的目的是利用SD-OCT评估不同病因的ME分布和特征。材料和方法：这项横断面观察性研究纳入了不同病因的ME患者。SD-OCT用于评估黄斑中央厚度、视网膜体积、囊样间隙（CS）、视网膜前膜（ERM）、高反射灶和视网膜内层紊乱（DRIL）。结果：54%的研究参与者为女性，平均年龄为57岁。糖尿病（50.4%）是最常见的病因，其次是视网膜静脉阻塞、年龄相关性黄斑变性、ERM和炎症。CS占49.6%，drl占48%。严重的视力损害在糖尿病和血管闭塞的病例中更为常见。结论：SD-OCT能有效识别ME不同病因的结构模式，有助于诊断和制定治疗计划。
