Multimodal imaging features of non-proliferative and proliferative diabetic retinopathy based on SD-OCT and fundus autofluorescence

Spectral-domain optical coherence tomography and FAF provide complementary information for evaluating structural and functional retinal alterations in DR. FAF is particularly useful for visualizing hemorrhage, DME, and fibroproliferative membranes. In contrast, SD-OCT enables detailed assessment of multiple retinal biomarkers. The high prevalence of epiretinal membranes highlights their potential role in DR progression.
