研究目的:

比较不同分组受试者治疗6个月后黄斑中心凹厚度(Central Foveal Thickness, CFT)、最矫正视力(Best Corrected Visual Acuity, BCVA)的变化值,以及视网膜结构病变的(如渗出、出血)改善、视力稳定/恶化率、微血管形态特征与血流动力学参数、安全性等关键指标,系统评估联合方案在改善糖尿病黄斑水肿(Diabetic Macular Edema, DME)患者视功能和解剖结构指标上的临床价值,验证康柏西普联合递法明片是否优于单纯康柏西普治疗DME,为DME患者提供优效治疗方案。  

Objectives of Study:

To compare the changes in central foveal thickness and best corrected visual acuity, as well as key indicators such as retinal structural improvement, rate of vision stability or deterioration, microvascular morphology and hemodynamic parameters and safety, among different subject groups after six months of treatment, systematically evaluate the clinical value of the combination regimen in improving visual function and anatomical structural outcomes in patients with diabetic macular edema(DME), verify whether intravitreal injection of conbercept plus oral administration of difrarel is superior to intravitreal injection of conbercept alone in treating DME, and thereby provide an optimized therapeutic strategy for patients with DME.

Severe systemic diseases (e.g., cardiovascular, cerebrovascular, hepatic or renal insufficiency) or other conditions that the investigator deems unsuitable for enrollment; 6. Pregnant or lactating women; 7. Non-study eye with loss of function, defined as best-corrected visual acuity (BCVA) of hand motion or worse, or patients with only one functional eye.
