Abstract
Diabetic retinopathy (DR) is a progressive neurovascular complication of diabetes and a major cause of preventable visual impairment. Although intravitreal anti-vascular endothelial growth factor therapy, corticosteroids, laser photocoagulation, and vitreoretinal surgery have improved outcomes, treatment burden, cost, invasiveness, variable response, and limited access sustain interest in complementary strategies. Herbal-derived compounds, including curcumin, resveratrol, quercetin, anthocyanins, crocin, naringin, baicalein, and berberine, target several mechanisms implicated in DR, such as oxidative stress, inflammation, blood-retinal barrier failure, angiogenesis, mitochondrial dysfunction, and retinal neurodegeneration. However, biochemical or histological improvement does not automatically establish clinically meaningful retinal benefit. Multimodal imaging can provide objective structural and vascular endpoints that connect pharmacological mechanisms with tissue-level response. This narrative review integrates experimental and clinical evidence on herbal-derived therapies with color and ultra-widefield fundus photography, optical coherence tomography (OCT), OCT angiography (OCTA), fluorescein angiography, adaptive optics, and emerging quantitative imaging. Preclinical findings are consistently favorable, but human imaging evidence remains limited. Notably, an OCTA-based randomized trial of curcumin-piperine improved systemic oxidative-stress markers without significant OCT or OCTA change, whereas recent animal studies reported improved retinal structure and vascular density. This contrast illustrates the central translational gap. Future studies should use standardized extracts, pharmacokinetic characterization, prespecified imaging endpoints, centralized image grading, adequate follow-up, and comparison with standard care. Herbal-derived products should currently be considered investigational adjuncts rather than replacements for established DR therapy.
