Abstract
Purpose: To evaluate the role of intrasilicone oil injection of methotrexate (MTX) at the end of vitrectomy surgery for rhegmatogenous retinal detachment (RRD) associated with proliferative vitreoretinopathy (PVR). Methods: In this prospective comparative study, pars plana vitrectomy and retinal reattachment were performed for eyes with RRD with grade C PVR. In the MTX group, 250 µg MTX was injected into the silicone oil at the end of surgery. The rate of retinal redetachment associated with PVR was assessed. Results: In total, 44 eyes of 44 patients (22 in the MTX group and 22 controls) were included. Baseline characteristics were similar between the two groups. Retinal redetachment occurred in one eye (4.5) in the MTX group and five eyes (22.7) in the control group (p = 0.18). The change in visual acuity was similar between the two groups at final visit (p = 0.15). Conclusion: The rate of redetachment associated with PVR was lower after intrasilicone injection of MTX at the end of vitrectomy for RRD with severe PVR compared to control group; however, the difference was not statistically significant. © 2019, © 2019 Taylor & Francis Group, LLC
