Anatomical and visual outcomes of retinectomy in eyes with advanced proliferative vitreoretinopathy

Abstract

Background: Visual and anatomical success of inferior retinectomy in proliferative vitreoretinopathy complicating recurrent retinal detachment (RD). Aims: The aim of this study was to evaluate anatomical and visual outcomes of retinectomy in eyes with recurrent RD with advanced proliferative vitreoretinopathy. Settings and Design: Institutional, observational, cross-sectional retrospective study. Subjects and Methods: Records of 56 eyes of 56 patients with recurrent RD and proliferative vitreoretinopathy (PVR) were evaluated, three-port incision sclerotomies followed by standard vitrectomy were done. Retinal reattachment was achieved with the aid of perfluorocarbon and retinectomy. Retinectomy was performed at the time of surgery based on retinal shortening (inferior 180°). Silicon oil (SO) was used as a tamponade. Retinal attachment and visual acuity (VA) after 6 months were evaluated. Statistical Analysis Used: Chi-squared test. Results: In all 52 of 56 (93%) eyes, retinal reattachment was successful, with a mean follow-up of 25 months (range, 6–70 months). After retinal reattachment, VA improved or stabilized in 39 of 56 patients (70%). Conclusion: When combined with anterior base dissection, inferior retinectomy may be useful in the surgical treatment of complex PVR-related RD. It was found that with lensectomy, radical anterior base dissection, and inferior retinectomy, anatomic success rates are improved and visual function can be maintained.
