Radial peripapillary capillary changes and retinal nerve fiber layer alterations in diabetic foot ulcers with mild-to-moderate nonproliferative diabetic retinopathy: an OCTA study

The study underscores notable alterations in RPC density and RNFL thickness among patients with DFUs and mild-to-moderate NPDR. These alterations may reflect systemic microvascular impairment, potentially exacerbated by systemic inflammation, or changes suggestive of reactive gliosis, though further validation is needed. These findings underscore the need for early ophthalmological evaluation and a comprehensive approach to managing both peripheral and ocular diabetic complications. Future studies incorporating systemic inflammatory biomarkers and functional visual assessments are needed to explore the mechanisms underlying these retinal changes.
