Purpose: Evaluation of efficacy and safety of 23 – guage five ports vitrectomy versus 23 – guage three ports
pars plana vitrectomy (PPV) in diabetic tractional retinal detachment.
Study Design: Prospective Interventional case series.
Place and Duration of Study: Mayo hospital and Services hospital, Lahore, from February 2018 to December
Material and Methods: Forty eyes of forty patients were equally divided into two groups. One group which
underwent five ports PPV and the other group had three ports PPV. Patients with tractional retinal detachment
(TRD) with fibrovascular membranes were included and patients who had undergone previous ocular surgery
(except cataract surgery) or having TRD due to other ocular diseases were excluded. Preoperative work-up
included visual acuity, intra ocular pressure measurement and slit lamp examination of anterior and posterior
segment. Gender, age, pre-operative and post-operative BCVA and intraocular pressure presented by calculating
frequency and percentages.
Results: Pre-operative BCVA improved from 1.11 ± 0.5 to 0.66 ± 0.5 in 3-port groups and from 1.7 ± 0.9 to 0.87
± 0.8 in 5-port groups. Duration of surgery was 74.40 ± 5.4 and 53.40 ± 2.5 minutes in 3 ports and 5-ports group
respectively. Iatrogenic retinal tear developed in two patients in each group. Per-operative vitreous hemorrhage
developed in three patients in 3-ports group and in two patients in 5-ports group. Two patients in each group
developed post vitrectomy cavity hemorrhage.
Conclusion: Bimanual 5- ports 23-guage vitrectomy is a faster procedure than three ports 23 – guage vitrectomy
in diabetic tractional retinal detachment.
