Background: There is a prevalent cause of blindness among the working population: diabetes retinopathy. Vitreous hemorrhage, extensive fibrovascular proliferation, traction retinal detachment, and traction-induced rhegmatogenous retinal detachment are among the late complications of proliferative diabetic retinopathy (PDR).The aim of this work was to assess frequency of complications and the visual prognosis following Pars Plana Vitrectomy (PPV) in cases of diabetic vitreous hemorrhage that underwent early versus delayed vitrectomy.
Methods: This prospective clinical trial was carried out on 30 patients with type 2 diabetes mellitus (T2DM) diagnosed with PDR complicated by simple vitreous hemorrhage assigned into two equal groups; early vitrectomy group and deferred vitrectomy group.
Results: Postoperative BCVA improved markedly in both groups, with the early vitrectomy group showing significantly better vision than the deferred group, while preoperative BCVA was comparable between them. Postoperative IOP increased significantly only in the deferred group, while the early group showed no notable change. However, overall comparisons between the two groups revealed no significant differences in preoperative, postoperative, or percentage change in IOP.
Conclusions: Early PPV for PDR-related VH yielded superior postoperative BCVA without increasing complications compared with deferred surgery, supporting earlier intervention in suitable candidates.
