研究目的:

本研究旨在通过前瞻性双盲随机对照试验,评估甲钴胺联合抗VEGF药物(康柏西普)对RVO-ME患者视网膜神经血管单元(NVU)修复的协同效应,结合多模态影像技术(OCT/OCTA/自适应光学/微视野/多焦ERG)动态分析神经血管整合的时空特征。评估甲钴胺联合抗VEGF治疗对RVO-ME患者黄斑中心凹厚度(CFT)和最佳矫正视力(BCVA)的改善效果。验证甲钴胺对神经血管单元(NVU)修复的综合作用,通过多模态影像学(OCT/OCTA/自适应光学)量化视网膜结构-血流-功能的协同修复  

Objectives of Study:

This study aims to evaluate the synergistic effect of mecobalamin combined with anti-VEGF drugs (conbercept) on the repair of retinal neurovascular units (NVU) in patients with RVO-ME through a prospective, double-blind, randomized controlled trial. The spatiotemporal characteristics of neurovascular integration are dynamically analyzed by combining multimodal imaging techniques (OCT/OCTA/ adaptive optics/micro-field of view/multifocal ERG). To evaluate the improvement effect of mecobalamin combined with anti-VEGF treatment on macular foveal thickness (CFT) and best corrected visual acuity (BCVA) in patients with RVO-ME. To verify the comprehensive effect of mecobalamin on the repair of the neurovascular unit (NVU), and quantify the synergistic repair of retinal structure - blood flow - function through multimodal imaging (OCT/OCTA/ adaptive optics)
