Treatment Strategy for Macular Edema with Ischemic Retinal Vein Occlusion

In recent years, with unhealthy eating habits and aging of society, there has been an increase of lifestyle-related diseases such as hypertension, hyper lipidemia, and diabetes, which are important risk factors for retinal vein occlusion (RVO), including branch RVO (BRVO) and central RVO (CRVO). Affecting an estimated 180,000 eyes per year in the United States, BRVO and CRVO comprise the second mostcommon type of retinal vascular disorder after diabetic retinopathy [1] BRVO accounts for approximately 80% of cases, but both types of RVO contribute to significant loss of vision, mostly as a result of macular edema [1,2]. The macula is the important part of the retina for detailed vision, especially the fovea that consists entirely of cones [3]. Therefore, BRVO and CRVO are potentially serious retinal diseases that can lead to severe visual impairment.
