To assess the anatomic and functional outcomes of long-term silicone oil (SO) tamponade and its complication rates.
We retrospectively reviewed 98 eyes of 97 patients with intraocular SO (Oxane 5700 Bausch & Lomb, Kingston-upon-Thames, UK) for at least 12 months. Clinical data and any SO-related complications were recorded from the notes at baseline, and at months 3, 6, 12 and last follow-up. We defined the ambulatory vision as visual acuity of 4/200 (logMAR 1.7) or better.
Mean age was 55.2±17.4 years, and mean duration of silicone oil in the eye was 30.2±20.9 months. The main reasons for long-term SO tamponade were ocular trauma (22.4%), retinal redetachment (19.4%), uveitis (13.3%), and proliferative diabetic retinopathy (10.2%). Anatomic success (flat retina) and ambulatory vision were achieved in 65 and 36 eyes respectively at last follow-up. The common complications were optic neuropathy (13.3%), corneal decompensation (9.2%), hypotony (8.2%), and band keratopathy (5.1%). Accessed separately according to the reason for long-term SO, anatomic success rates were relatively high in retinal redetachment (79.0%) and uveitis (76.9%), and low in severe proliferative vitreoretinopathy (55.6%) and trauma (50.0%) cases. The rates of under-ambulatory vision were 100%, 66.7, and 66.7% in trauma, endophthalmitis, and severe proliferative vitreoretinopathy respectively.
The long-term SO tamponade can be a last resort option in complex cases. But the anatomic and functional success rates were low due to the various SO-related complications. The prognosis was especially poor in trauma and severe proliferative vitreoretinopathy cases.
