Treatment of Localized Retinal Redetachment in Silicon Oil Filled Eyes

Purpose: To assess the success rate of retinal reattachment surgery in localized re-detachment in Silicon oil filled eyes which had previously undergone primary retinal detachment (RD) repair with pars plana vitrectomy (PPV) with silicon oil. Study Design: Retrospective cross sectional case series. Place and Duration: Farooq Hospital and Medicare eye centre, Lahore from October 2016 to November 2017. Material and Methods: All those patients were included in our study who underwent primary retinal attachment surgery with pars plana vitrectomy (PPV) and silicon oil for complicated retinal detachment as an internal tamponade and later presented with localized inferior retinal detachment within 6 months of previous RD repair. Patients with total detachment, extensive PVR, retinal shortening, gas tamponade, total Re RD, and external scleral buckle were excluded. Two ports were made under local anesthesia instead of three conventional ports, simple non irrigation vitrectomy technique was used to achieve retinal reattachment under silicon oil without exchange of SO. Results: Ten eyes of ten patients were included, eight (8) males and two (2) females. The age range was from 18 to 79 years. Most common cause of re detachment (RD) in all cases was proliferative retinopathy (PVR) followed by retinal break. The new retinal break was identifiable in three (3) cases. All cases attained anatomical success in term of complete retinal attachment after second operation in one year follow up period. Conclusion: Simple non irrigation vitrectomy surgical technique under local anesthesia is effective, economical and time saving as compared to complicated three port vitrectomy with oil exchange.
