Dimopoulos S, William A, Voykov B, et al. - Researchers conducted this retrospective analysis to contrast vitrectomy with conventional silicon oil (CSO) combined with an encircling band (EB) and vitrectomy with heavy silicon oil (HSO) alone to treat retinal re-detachment by inferior PVR, where standard procedures have already failed. The sample consisted of patients with inferior complex re-detachment with secondary PVR after primary surgery, who received pars plana vitrectomy (PPV) with CSO combined with EB (group 1) or PPV alone with HSO (group 2) between December 2006 and August 2017. One hundred nineteen eyes included in this report. Combining PPV with EB can lead to better anatomical (SSAS, FAS) and functional success compared to PPV alone with HSO for complicated retinal re-detachment through inferior PVR. Serious complications in both groups were comparable.
