Aim: To introduce the symptoms, risk factors of sub-conjunctival Silicone Oil (SO) and evaluate a new technique to remove sub-conjunctival SO in an out-patient setting. Methods: Retrospective study: Patients demonstrated sub-conjunctival SO nodules after 23-gauge trans-conjunctival suture-less Pars Plana Vitrectomy (PPV) with SO tamponade were treated by 26-gauge syringe needle in an outpatient setting. Data such as signs, symptoms, and risk factors for SO leaking, slit lamp examination were collected. Results: 32 patients (32 eyes) were observed in the study. Slit lamp exam found obvious subconjunctival SO blebs near previous SO injection sites in all subjects. Anterior segment OCT revealed the buildup of SO nodules due to poor scleral wound healing. The risk factors for SO leaking and found that the duration of the operation, multi-operation, history of pathological myopia, diabetes and high IOP post-operation are major risk factors. All sub-conjunctival SO blebs were removed by 26-gauge syringe needle clearly. The discomfort of surgical eyes significantly reduced after removal of sub-conjunctival SO. Conclusion: Our method of removing sub-conjunctival SO blebs using 26-gauge syringe needles was found to be safe and effective in an outpatient setting.
