In patients with regressed PDR following complete PRP, the timing of vitrectomy for non-clearing vitreous hemorrhage depends on the patient's overall visual needs, fellow eye status, etc. In such patients, assuming the ultrasound shows the retina to be attached, I consider the vitrectomy to be a non...
