Purpose:
To investigate the prognostic factors for recurrent rhegmatogenous retinal detachment following silicone oil removal.
Methods:
This retrospective review included 147 consecutive patients with rhegmatogenous retinal detachment treated with silicone oil tamponade at a high-volume referral-based tertiary hospital between January 2012 and May 2022. All patients underwent follow-up for a minimum of 6 months after subsequent silicone oil removal. The primary outcome measure was the rate of recurrent retinal detachment following silicone oil removal, and the secondary outcome was best-corrected visual acuity after silicone oil removal.
Results:
The mean silicone oil tamponade duration was 4.7 ± 5.01 months (range, 1-38 months; median, 3 months), and the recurrent retinal detachment rate after silicone oil removal was 15.6%. Logistic regression analysis revealed that argon endolaser photocoagulation during silicone oil removal (odds ratio [OR], 0.309; 95% confidence interval [CI], 0.106-0.898; p = 0.031) was associated with a lower rate of anatomical success after silicone oil removal. Demographics, preoperative ocular characteristics, proliferative vitreoretinopathy, previous scleral encircling or buckling, previous retinectomy, concomitant phacoemulsification, duration of silicone oil tamponade, and gas tamponade after silicone oil removal were not significantly associated with recurrent retinal redetachment after silicone oil removal. Duration of silicone oil tamponade (OR, 1.226; 95% CI, 1.073-1.402; p = 0.003) and recurrent retinal detachment after silicone oil removal (OR, 3.400; 95% CI, 1.311-8.817; p = 0.012) were associated with poor visual outcomes after silicone oil removal.
Conclusions:
Among all factors examined in this study, including the duration of silicone oil tamponade, laser retinopexy was the only significant prognostic factor for recurrent retinal detachment after silicone oil removal. A longer duration of silicone oil tamponade was associated with worse visual outcomes and a lower rate of visual improvement after silicone oil removal.
