Removal of dropped heavy silicone oil bubble using air

Abstract

Purpose: To report a new ‟rescue" technique for the removal of a dropped heavy silicone oil (HSO) bubble, after failed aspiration with a short, 23-gauge cannula and suction pump. Methods: If the HSO bubble is dropped during standard, 23-gauge, transconjunctival extraction with a suction pump, filtered air can be injected into the HSO bubble to make it rise. Extraction can then be resumed with the suction pump, resulting in complete removal of HSO. Results: This technique has been used approximately ten times over the last 18 months with a 100% success rate and no complications. Conclusion: We present a safe, simple, and cost-effective ‟rescue" method for the removal of a dropped HSO bubble using air. With the rise in popularity of HSO and the development of new heavy tamponades, safe and effective techniques for their removal are becoming increasingly important.
