Recent studies have demonstrated that neuroglial vascular unit (NGVU) injury leads to distinct fundus changes in DR, including exudates, cotton-fluff spots, microangiomas, hemorrhages, and neovascularization. Currently, the primary clinical treatment options primarily target retinal microvascular degeneration during the middle and late stages of DR through techniques such as retinal laser photocoagulation, antivascular endothelial growth factor (VEGF) therapy, and vitrectomy. However, progression to these stages often results in irreversible damage to visual acuity with limited treatment efficacy. In recent years, relevant research has confirmed that NGVU injury occurs prior to retinal microangiopathy in patients with DR, and it is closely associated with impaired visual function. Therefore, targeting NGVU holds potential for future therapeutic interventions aimed at preventing and treating early-stage DR. This review identifies six key molecular targets (P2X7 receptor, NLRP3 inflammasome, retinal microglial cell necroptosis pathway, spermine oxidase, and AQP4-AS1 lncRNA) that mitigate NGVU dysfunction in preclinical models. Literature search was conducted in PubMed/Embase using keywords“diabetic retinopathy,” “neuroglial vascular unit,” and “targeted therapy” (2018–2024), focusing on preclinical studies within vivo efficacy data.  \nKeywords: diabetic retinopathy; inflammatory pathways; neuroglial vascular unit (NGVU); retinal neurodegeneration; targeted therapy  \n1. Introduction  \nThe prevalence of DR, a common ocular chronic microvascular complication of diabetes mellitus, is approximately 30%–40% among diabetic patients globally [1] . With rapid socioeconomic development, changes in dietary structure, and the aging global population, the global prevalence of DR is expected to continue increasing in the future [2] . It is projected that by 2045, the number of DR patients in China will reach approximately 174.4 million [3] . Prolonged diabetic disease can lead to retinal neurodegeneration and microvascular damage associated with DR, resulting in chronic vision loss, severe visual dysfunction, and even blindness. Current treatments such as retinal laser photoco-  \nagulation, vitreous injection of anti-VEGF agents, and vitrectomy have limited efficacy. As the disease progresses to an advanced stage, visual impairment often becomes irreversible. Long-term anti-VEGF treatment and repeated surgeries significantly increase the economic burden on both patients and society. Given the limited efficacy of current mainstream regimens for treating retinal neurodegeneration, microvascular damage, and disease progression associated with DR, it is crucial to explore therapeutic targets for preventing and treating early stages of DR progression.
