Changes of macular sensitivity and morphology after pars plana vitrectomy for macular edema with central retinal vein occlusion: a case series

摘要

BackgroundIt is unclear how retinal ischemia influences the changes of visual acuity, macular sensitivity, macular thickness, and macular volume after the performance of pars plana vitrectomy (PPV) for macular edema in patients with central retinal vein occlusion (CRVO).
