Early vitreoretinal surgery on vascularly active stage 4 retinopathy of prematurity through the preoperative intravitreal bevacizumab injection

Abstract

Intravitreal bevacizumab administrated prior to vitrectomy effectively reduced active neovascularization in vascularly active stage 4 ROP patients, thus advancing the timing of vitrectomy and facilitating pars plicata vitrectomy (PPV).
