[Research progress on scleral perforating vessels in the formation of myopic choroidal neovascularization].

Myopic choroidal neovascularization (mCNV) is a severe complication of pathological myopia. Currently, the primary treatment involves anti-vascular endothelial growth factor (VEGF) therapy, which significantly improves visual acuity in mCNV patients. However, challenges such as high recurrence rates and inconsistent therapeutic outcomes persist. Previous studies attributed mCNV to choroidal thinning and ischemia. Recent research suggests that, in addition to choroidal factors, perforating scleral vessels (PSV) are closely associated with the occurrence and therapeutic efficacy of mCNV. This review comprehensively explores the definition of PSVs, their imaging classifications and features, as well as their intricate connections with the occurrence and clinical outcomes of mCNV. By delving into the role and potential mechanisms of PSVs in mCNV, this review aims to deepen our understanding of their involvement in this condition.
