Abstract: Retinal vein occlusion(RVO)is the most common retinal vascular disease and one of the most common causes of blindness. The incidence of RVO increases with age. Most patients are over 65 years old, but the age of onset of the disease is also getting younger because of changes in the Chinese diet. Macular edema, often accompanied by retinal vein occlusion, is also a major cause of vision loss in patients with the disease.At present, there are many treating approaches for the patients with retinal vein occlusion combined with macular edema. Each method has its different effects due to the individual differences of the patients. To date, different treatment schemes are conducted according to the patients' own conditions, and most of them are combined with several treatment methods. By consulting relevant literatures and personal experience in the process of treating patients, the author summarizes and discusses the prospects of the treatment methods, curative effects, prognosis and costs of retinal vein occlusion complicated with macular edema, so as to find potential problems and influencing factors and explore the best clinical treatment regimen.
