Retinotomy and Retinectomy in the Management of Rhegmatogenous Retinal Detachment Associated with Advanced Proliferative Vitreoretinopathy

PURPOSE: To report the anatomical and functional outcomes of retinotomy and/or retinectomy for the management of rhegmatogenous retinal detachment (RRD) complicated by advanced proliferative vitreoretinopathy (PVR). METHODS: In this retrospective study, the charts of patients who underwent pars plana vitrectomy with retinotomy and/or retinectomy for the management of RRD complicated by PVR were reviewed. Primary outcome measures were final best-corrected visual acuity (BCVA) and anatomical reattachment rate. RESULTS: Sixty-one eyes of 61 patients with a mean age of 48.56 ± 15.92 were studied. The mean follow-up time was 21.38 ± 23.08 months. The mean angle of the retinotomy was 171.31° ± 79.15°. Thirty-two (52.5%) of them needed extensive (≥180°) retinotomy. In addition, simultaneous retinectomy was performed in 36.2% of the cases. The BCVA was 2.18 ± 0.63 and 1.85 ± 0.71 logMAR before the surgery and at the last visit, respectively (P = 0.001). The initial anatomical success was achieved in 45 eyes (73.8%) after retinotomy surgery. Sixteen eyes (26.2%) had recurrent RD and needed reoperation, which was performed 5.60 ± 4.01 months after the initial retinotomy surgery. At the last examination, the retina was attached in all patients. CONCLUSION: Retinotomy with/without retinectomy is an effective procedure in the majority of patients with RRD associated with advanced PVR; however, additional surgeries are needed in a significant number of eyes to achieve final anatomical success.
