Diabetic retinopathy (DR), a leading cause of blindness, is driven by hyperglycemia-induced neurovascular damage. Emerging evidence indicates that PANoptosis, an integrated inflammatory programmed cell death modality encompassing apoptosis, pyroptosis, and necroptosis, participates in the progression of diabetic retinal damage; however, the supporting evidence varies substantially across clinical specimens, diabetic animal models, high-glucose cultured retinal cells, and non-DR inflammatory dise
