Combined perfluoropropane gas and viscoelastic material injection for anterior chamber reformation following trabeculectomy.

AIM To describe a novel technique to treat hypotony and shallow anterior chamber following trabeculectomy METHODS Three patients who underwent fornix based trabeculectomy with mitomycin C (MMC) presented in the postoperative days with a shallow anterior chamber, hypotony, and overfiltrating blebs. They were treated with an injection of 0.2 ml of 16% perfluoropropane (C(3)F(8)) to the anterior chamber followed by an injection of a viscoelastic material. RESULTS In all patients the anterior chamber was reformed successfully without any complications. CONCLUSIONS Patients with a shallow anterior chamber and overfiltrating blebs following a recent trabeculectomy can be treated successfully with a combination of a long acting gas and a viscoelastic material.
