Abstract

Purpose : Purpose: Temporary intraocular tamponade with silicone oil is widely used in the treatment of complex retinal detachments (RD). Optimal timing for removal of silicone oil (ROSO) is not clearly defined and redetachment rates following ROSO vary from 9% to 33%. This study aims to look at how anatomic and functional outcomes correlate following ROSO association of outcomes to duration of tamponade.

Methods : Methods: We report a retrospective case series of (n= 166) eyes of (n= 165) patients with intraocular silicone oil tamponade over a 4 year period at a tertiary referral centre. All operations were carried out by two vitreoretinal surgeons. Indication for the use of silicone oil were complex retinal detachment associated with PVR, ocular trauma, giant retinal tears, and others. Statistical analysis was carried out using IBM SPSS Statistics.

Results : Results: Silicone oil was removed from 84 eyes (64%) with the duration of intraocular silicone oil tamponade ranged from 20 days to 30 months with a mean duration of 6.9 months. 9 eyes (10.7%) underwent oil exchange for re detachment under oil. 9 eyes (10.7%) re detached following ROSO requiring further surgery with repeat silicone oil tamponade. Final anatomic outcome was the retinal status at the patients last follow up visit. In terms of functional outcomes n= 130 eyes who underwent silicone oil tamponade and had a final VA documented (106) with 80% showing an improvement or stability in BCVA from baseline

Conclusions : Discussion: Attachment rate of 89.3% in this series correlates well with results in the literature. In this series, mean duration of oil tamponade in the attached group (n=73) was 7.5 months and in the detached group (n=9) was 5.5 months however duration of silicone oil tamponade was not significantly associated with redetachment rates(95% CI =0.89-1.4, p= 0.204). Patients who underwent ROSO showed an improvement in final BCVA compared to those with oil in situ at final follow up visit (60.5 % improved versus 55 % respectively).2 patients showed a sudden and profound drop in BCVA following ROSO. These results add to published data on outcomes following ROSO in particular correlation between functional and anatomic outcomes which guides the management of complex RD.
