Abstract
Purpose: The purpose of this study was to evaluate difference in the surgical outcome for management of giant retinal tear (GRT) by pars plana vitrectomy (PPV), with and without encircling 240 band.
Methods: This was a randomised control study, 20 patients having GRT underwent PPV combined with encircling band in one group (A) and without band in group (B) along with laser retinopexy of the retina followed by silicon oil tamponade. All patients were followed up for at least 1 year.
Results: Complete success (retinal attachment after silicon oil removal) was achieved in 12eyes (80%), at the end of follow up, while incomplete success (where retina remain detached under silicon oil removal or redetached after SOR) was seen in 8 eyes (20%) patients. At the end of follow up improvement of best corrected visual acuity was achieved in 19 eyes. Preoperative best corrected visual acuity ranged from Hand movements(HM) to 6/60, while post operative visual acuity ranged from 6/9 to HM in group A and 6/18 to HM(hand movements)in group B.
Conclusion: GRT can be effectively treated with PPV along with encircling scleral band, 3600 laser retinopexy and silicon oil tamponade(1000cc and 5000cc in recurrent RD post SOR) with minimum incidence of recurrence.
