Assessment of retinal and choroidal structural and microvascular changes in early diabetic retinopathy using swept-source optical coherence tomography angiography.

ABSTRACT:

Objective

It was to assess changes in structural parameters in early diabetic retinopathy (DR).

Materials and methodologies

This study is a retrospective analysis that included patients with early DR admitted to the Affiliated Third Hospital of Nantong University from January 2024 to December 2024. The participants were divided into the non-DR group (NDR group) and the non-proliferative DR group (NPDR group, which included mild, moderate, and severe subgroups) using swept-source optical coherence tomography angiography (SS-OCTA) technology. One-way analysis of variance (ANOVA) and the Kruskal-Wallis test were used to compare parameter differences among the groups.

Results

A total of 208 diabetic patients were included (55 in the NDR group, 153 in the NPDR group) and 5
