[Deeply understanding the pathological characteristics of diabetic retinopathy and central retinal vein occlusion and the similarities and differences in therapeutic strategies].

Diabetic retinopathy (DR) and central retinal vein occlusion (CRVO) are both vascular diseases of the retina, accompanied by macular edema and complications caused by ocular ischemia, but the pathogenesis and course of these two diseases are quite different, so the treatments for them are susceptible to deviation and confusion. This article emphasizes the importance of fully understanding the pathogenesis and clinical characteristics of DR and CRVO, and elaborates on the treatment concepts and strategies, as well as the differentiation of treatment methods, with a view to identifying the differences in the diagnosis and treatment of DR and CRVO, and to providing guidance and reference for clinical work and improvement of diagnostic and treatment effects.
