Current therapy for retinal vein occlusion

Abstract

Retinal vein occlusion is a common retinal vascular disorder causing visual deterioration in the elderly.Vision-threatening complications include macular ischemia, neovascularisations, and vitreous hemorrhages. There are central and branch retinalvein occlusions as well as their ischemic and nonischemic subtypes. Branch occlusion and nonischemic cases are associated withbetter prognosis, often with good recovery of visual acuity. There have been various modes of therapy used for this disease butwith little or poor effect. Due to the lack of effective monotherapy for retinal vein occlusions, there is probably a need to combine the therapy approaches.
