Removal of Silicone Oil from the Anterior Chamber: New Technique

Abstract

Purpose: To describe a new technique of removal of silicone oil from the anterior chamber and to report the safety and effectiveness of the procedure.

Material and Methods: The prospective feasibility study of a new technique was concluded on twenty patients who presented with silicone oil in the anterior chamber postoperatively between six weeks to six months after complicated retinal detachment surgery. An air pump commonly used in vitreo-retinal procedures was connected with tubing to anterior chamber, which was entered by a twenty seven gauge needle. Air was pumped gradually (maximum pressure required to build-up was 40 mmHg) into the chamber with the foot pedal to push silicone posteriorly as well as across the anterior chamber to the opposite side. Simultaneously oil was egressed out through a self sealing corneal incision held open by depressing its posterior lip.

Results: 20 patients under went removal of silicone oil from the anterior chamber by this technique. The procedure was uneventful and complete removal of oil was accomplished in all patients.

Conclusion: The technique is simple, safe, effective and cheap for managing silicone oil in the anterior chamber.
