    Abstract:
    PURPOSE: To compare the safety and efficacy of removing 5000 centistokes silicone oil between 20-gauge and 25-gauge vitrectomy technique. METHODS: Prospective case series of 34 consecutive patients undergoing 5000 centistokes silicone oil removal using 20-gauge or 25-gauge cannulas. The main outcome measures were the safety and efficacy of silicone oil removal. The safety was evaluated by recording intraoperative and postoperative complication rates, including bleeding, recurrence of retinal detachment, hypotony, choroidal detachment, corneal edema, endophthalmitis, vitreous hemorrhage, conjunctival injection, and subconjunctival hemorrhage. The efficacy was judged by the ability to attain the complete removal of silicone oil and the total surgical time to complete the procedure. RESULTS: Sixteen patients underwent 20-gauge vitrectomy for the removal of 5000 centistokes silicone oil between January 2008 and January 2010, and 18 patients underwent 25-gauge vitrectomy for the removal of 5000 centistokes silicone oil from January 2010 to August 2012. Silicone oil was successfully removed completely in all cases. Using 25-gauge vitrectomy to remove silicone oil was significantly more time efficient with the mean total surgical time of 25 ± 6 minutes compared with 42 ± 10 minutes in 20-gauge vitrectomy group (P < 0.05). There were no differences in the intraoperative or postoperative complication rates between the two groups. None of the patients developed postoperative recurrence of retinal detachment, hypotony, choroidal detachment, corneal edema, endophthalmitis, or vitreous hemorrhage. CONCLUSION: Twenty-five-gauge silicone oil removal is safe and effective. Surgical time is significantly reduced using sutureless 25-gauge sclerotomies. This may translate to cost reduction by decreasing time spent in the operating room.
