Summary
Silicone oil removal (SOR) outcomes show a 15.7% re-detachment rate, but visual acuity improved in eyes without further repairs. Laser retinopexy may reduce re-detachment after SOR for complex retinal detachments.
Area of Science:
- Ophthalmology
- Retinal Surgery
- Vitreoretinal Interface
Background:
- Silicone oil (SO) is used for complex rhegmatogenous retinal detachment (RRD) repair.
- Outcomes following SO removal (SOR) require further investigation.
Purpose of the Study:
- To describe outcomes after SOR in eyes with RRD repaired using SO tamponade.
- To identify factors associated with re-detachment and visual acuity following SOR.
Main Methods:
- Retrospective analysis of 89 eyes undergoing SOR between 2016-2021.
- Exclusion of proliferative diabetic retinopathy and short follow-up (<3 months).
- Statistical analysis using ANOVA (p < 0.05).
Main Results:
- The re-detachment rate after SOR was 15.7% (14/89 eyes).
- Eyes receiving 360° laser retinopexy prior to SOR had fewer subsequent repairs (87.0% vs 33.3%, p=0.03).
- Final visual acuity improved by 3 EDTRS lines in eyes without re-detachment post-SOR (p=0.04). Persistent hypotony occurred in 6.7% of eyes.
Conclusions:
- Laser retinopexy may reduce re-detachment rates after SOR.
- SOR is associated with a 15.7% re-detachment rate and 6.7% hypotony.
- Visual acuity improved in eyes that did not require further RRD repair after SOR.
