The purpose of this study was to assess the effect of ranibizumab in reducing intraoperative vitreous haemorrhage during pars plana vitrectomy, thus facilitating surgery and improving its anatomical and functional results in patients with advanced proliferative diabetic retinopathy and traction retinal detachment.
