Outcomes of Retinectomy of 180° or more in Retinal Detachment with Advanced Proliferative Vitreoretinopathy

Aim: To study the functional and anatomic outcomes of retinectomy of 180° or more in eyes with rhegmatogenous retinal detachment (RD) with advanced proliferative vitreoretinopathy (PVR) Grade D. Materials and methods: A retrospective analysis of 51 eyes that underwent pars-plana vitrectomy (PPV) with 180° or more of retinectomy for RD with PVR Grade D was done. Main outcome measures included retinal reattachment, visual outcomes and complications at a follow-up of 12 months. Separate analysis for these parameters was also carried out for subgroup of one-eyed patients. Results: Overall retinal reattachment was achieved in 86.3% cases with mean improvement in BCVA of 0.59 ± 0.91 (statistically highly significant) at final follow-up. In subgroup of one-eyed patients (n = 11), retinal reattachment was achieved in 81.8% eyes with mean improvement of 0.52 ± 0.62 (significant) and 45.4% patients gained ambulatory vision. Main complications included recurrent PVR, optic atrophy, secondary glaucoma and hypotony. Conclusion: Retinectomies of 180° or more can help alleviate intractable traction in eyes with advanced PVR to achieve significant anatomical and functional improvement. This approach was found to be particularly valuable in one-eyed patients in order to achieve ambulatory vision.
