Research progress on factors associated with collateral vessel formation in branch retinal vein occlusion

Abstract:

Collateral vessels serve as a compensatory pathway for local circulatory disturbances induced by branch retinal vein occlusion(BRVO)and represent a manifestation of retinal capillary remodeling. The early establishment of these vessels plays an important role in improving the prognosis of visual function in patients with BRVO. This article systematically reviews recent domestic and international literature on the generation mechanism and influencing factors of collateral vessels. It aims to further reveal the anatomical structure and prognostic significance of collateral vessel formation, explore its clinical value in research, provide an evidence-based foundation for ischemic control in the clinical management of retinal vascular diseases, and offer novel insights for clinical diagnosis and treatment.
