Retinal vein occlusion

Retinal vein occlusion is a more common fundus vascular disease. Retinal vein occlusion is characterized by retinal blood stasis, retinal hemorrhage, and edema. Can be divided into central retinal vein occlusion and retinal vein branch occlusion. With the development of electron microscopy, laser and fundus photography, the etiology, classification, complications, prognosis and treatment of this disease have been further understood and improved, although the current treatment effect is not satisfactory.
