Diabetic vitreopapillary traction syndrome (DVPT) is an important complication of diabetic eye disease, caused by persistent mechanical traction exerted by the vitreous on the optic disc and its surrounding tissues, It can lead to severe consequences such as visual impairment and visual field defects. The core mechanisms involve diabetic vitreous remodeling (including hyperglycemia-induced vitreous liquefaction, abnormal cross-linking, and anomalous posterior vitreous detachment) and the fibrovascular proliferation-traction vicious cycle, both contributing to the initiation and progression. Regarding diagnosis, optical coherence tomography is the cornerstone for visualizing vitreo-papillary anatomical relationships. B-scan ultrasonography is valuable in cases with opaque media. Visual field testing assesses the extent of retinal nerve fiber layer involvement. Fluorescein fundus angiography reveals disruption of the blood-retinal barrier on the optic disc surface. Optical coherence tomography angiography shows promise as a novel tool for early diagnosis and dynamic monitoring by quantifying microvascular abnormalities in the optic disc region. For treatment, conservative observation is suitable for patients with mild symptoms and stable visual function. For those experiencing progressive visual impairment, significant disc edema, or concurrent complications of diabetic retinopathy requiring intervention, active consideration of pars plana vitrectomy is warranted. Future research can focus on neuroprotection and revasrearization strategies, the quantitative relationship between traction intensity and optic nerve injury, and the optimization of individualized treatment strategies based on mechanisms, thereby further improving the diagnosis and treatment level of DVPT.
