To report factors affecting the retinal redetachment rate after silicone oil removal (SOR) following rhegmatogenous retinal detachment (RRD) repair. Retrospective cohort study from December 1, 2014, to March 1, 2020, of 205 consecutive patients treated for RRD with silicone oil (SO) tamponade and subsequent SOR with at least 6-month follow-up. Primary outcome measure was the rate of retinal redetachment after SOR. The retinal redetachment rate after SOR was 18.5%. Preoperative macula and lens status, proliferative vitreoretinopathy, previous retinectomy, retinal detachment size, concomitant phacoemulsification, previous scleral buckling, and endolaser during SOR did not affect the redetachment rate after SOR. Previous SO exchange was associated with increased redetachment (OR 2.53, 95% CI [1.11-5.80], P = 0.0278). Twelve months of SO tamponade had lower redetachment rates compared with 3 months (OR 0.25, 95% CI [0.04-0.09], P = 0.048). Shorter SO tamponade (3 vs. 12 months) had better final visual outcomes after SOR (0.80 ± 0.61 vs. 1.41 ± 0.66, P < 0.0001). No preoperative or intraoperative factors in this analysis influenced the risk of redetachment after SOR except duration of SO tamponade and previous SO exchange. Although longer SO tamponade duration may be associated with lower rates of redetachment, visual outcomes may be worse.
