Ophthalmol Update Jan ;14(2):30-2.

Objective: To report frequency of postoperative vitreous hemorrhage after pars plana vitrectomy for proliferative diabetic retinopathy. Material & Methods: This prospective case series was conducted from January 20015 to December 2015 at Al-Ibrahim Eye Hospital, Karachi. Patients diagnosed as ADED and advised PPV were selected for this study. Three port pars plana vitrectomy (23G) was performed. After removal of traction retinal bands (TRB) the minor retinal breaks were treated with argon laser and C3F8 tamponade. Tractional retinal detachment (TRD) was treated with removal of TRB, laser and Silicon oil tamponade. Results: This study analysed 106 eyes of 106 patients Primary vitrectomy was performed using C3F8 in 16 eyes (15.1%), silicon oil in 42 eyes (39.6%) and balanced salt solution (BSS) in 48 eyes (45.3%) as internal tamponade. Post-vitrectomy vitreous hemorrhage (PVH) occurred in 15.09% (16 patients) of these, Five patients 4.7% at 1st postoperative week and 11 patients (10.37%) at 3 months. None of the patients showed re-bleeding between 3-6 months. Hemorrhage presenting early resolved by third month where as 9 out of 11 late bleeders resolved by 6 months. Remaining two eyes had to be reoperated. Conclusion: Postoperative VH was not uncommon after PPV for ADED. However, only a minority of patients required reoperation.
