Hasegawa T, et al. - The relationship between the clinical findings and the response to ranibizumab therapy in eyes with macular edema associated with branch retinal vein occlusion was determined in this analysis. The medical records of 68 patients with macular edema associated with a branch retinal vein occlusion were reviewed. The findings from the present study suggested that the dye leakage pattern in the fluorescein angiography images and choroidal thickness could be correlated with response to ranibizumab therapy.
