In this study, the ischemic index and vascular leakage index, and the effect on macular edema and neovascularization in retinal vein occlusion will be evaluated by ultra-wide field fluorescence angiography (UWFA). UWFA has a wider range than conventional angiography, and can clearly observe the peripheral retina. The purpose of this study is to quantitatively analyze these changes and investigate the effect on macular edema and neovascularization secondary to retinal vein occlusion.
