Comparison of Two Techniques of Passive Silicone Oil Removal.
Ophthalmol Update Jan ;14(2):44-7.

Purpose: To evaluate the safety and efficacy of two different techniques of passive removal of silicone oil with 23-gauge (G) trans-conjunctival suture less system. Methods: This is a single-center, prospective, interventional, randomized control study. Hundred eyes of 100 patients were enrolled in this study and randomized into 2 groups. Group 1 (n = 50) underwent 23 G passive removal of silicone oil with infusion cannula connected to the VGFI(Vented gas fluid infusion) pump, and the infusion pressure was maintained initially at 15 mm Hg. Passive Silicone oil removal (SOR) was done by increasing the VGFI pressure to 30 mmHg. Group 2 (n = 50) patients underwent passive removal of silicone oil with 23-G trans-conjunctival sutureless system. Time for silicone oil removal was recorded and postoperative hypotony, redetachment rate and endophthalmitis were observed. Results: Silicone oil removal time was significantly shorter in Group 1 than in Group 2. Both groups were similar in safety in terms of chance of endophthalmitis, re-detachment rate, and postoperative hypotony. Conclusion: Passive removal of silicone Oil with 23-G transconjunctival suture less system with infusion cannula connected to vented gas fluid infusion(VGFI) hastens removal of silicone oil. It is a safe and effective procedure in 1000 centistokes silicone oil removal.
