AIM: To study the various indications, anatomical results, functional visual outcomes, and safety of pars plana vitrectomy (PPV) in complications of proliferative diabetic retinopathy (PDR). Materials and Methods: This was a prospective interventional study performed on patients presenting at the Retina Clinic of a tertiary care eye hospital in Tamil Nadu between April 2012 and June 2013. All eyes undergoing PPV for complications of PDR and having adequate follow up were included. Data collected included indications for PPV, type of surgery performed, intra and post-operative complications, anatomical outcomes and visual results following surgery. Results: 47 eyes of 46 patients were included in the study. Most common indications for surgery were non-clearing vitreous hemorrhage and tractional retinal detachment (TRD) threatening the macula. Visual acuity improved significantly following surgery across all indications for surgery (p=0.003). Visual acuity continued to improve during follow-up period (p=0.00004). Rate of visual recovery was slower with eye with TRD as compared to other indications. Retina was attached at last follow up in 89% of eyes. Most common complications encountered were 8% eyes had severe intraoperative bleeding and 17% eyes had iatrogenic retinal break, post-operatively 6% of eyes developed recurrent vitreous hemorrhage and retinal break and one eye developed combined rhegmatogenous and tractional retinal detachment. Conclusions: PPV in eyes with visual loss due to complications of PDR can offer significant improvement in visual acuity. However, surgery in these eyes may be associated with vision threatening complications.
