Time course of changes in contrast sensitivity following intravitreal ranibizumab injection for branch retinal vein occlusion

To evaluate contrast sensitivity (CS) in patients with branch retinal vein occlusion (BRVO) following intravitreal ranibizumab injection (IVR), and to investigate the relationship between CS and retinal microstructure. A retrospective, observational case series. We included 23 eyes with treatment naive BRVO followed up for 6 months after treatment. Best-corrected visual acuity (BCVA), letter contrast sensitivity (LC), and 10% low contrast visual...
