Abstract

Purpose: To outline the features, results and associated complications following the removal of silicone oil from the eyes.

Methods: This is a retrospective study of eyes treated for silicone oil removal between 2017 and 2021. Visual acuity (VA), intraocular pressure (IOP) and rates of retinal re-detachment, hypotony, ocular hypertension, corneal complications, cystoid macular oedema (CMO) and cataract progression were evaluated. Several variables were analysed, including preoperative and postoperative visual acuity (VA) (at 1 month, 3 months and 6 months), preoperative and postoperative intraocular pressure (IOP) (at 1 month, 3 months and 6 months), and the prevalence of complications after silicone oil removal. The complications investigated were mainly retinal re-detachment, ocular hypotony, ocular hypertension, corneal complications, cystoid macular oedema (CMO), macular hole and cataract progression.

Results: Totally, 59 eyes of 59 patients (83% male, average age 42.9 years) were identified. Silicone oil tamponade had been used for retinal detachment (RD) surgery as a tamponade agent in all eyes, including two that had also had surgery for an open globe injury. Salt solution (BSS) or air were chosen as vitreous substitutes in the majority of eyes (85%) after removal of the oil. The average duration of SO tamponade was 16.1 months. The average logMAR VA before oil removal was 1.55. which improved to an average of 1 post-operatively. The average IOP pre-operatively was 18.9 mm Hg, which reduced by 4.6 mm Hg after surgery. Complications following SO removal were: retinal re-detachment (12%), CMO (8%), ocular hypertension (7%), hypotony (5%), cataract progression (5%), macular hole (5%), corneal complications (3%), and epiretinal membrane (3%).

Conclusion: Following SO removal, as shown in this study, VA has significantly improved overall and IOP has been reduced. In this study, the two most prominent complications encountered were Re-detachment and ocular hypertension.
