Hypotony may complicate fistulizing surgery in the immediate postoperative period due to excessive leakage through the fistula.1 This often results in the formation of choroidal detachments, which are complicated by increased uveoscleral outflow of aqueous humor into the suprachoroidal space and further hypotony.2 Also, hypotony in aphakic eyes carries the added risk of delayed nonexpulsive suprachoroidal hemorrhage.3 Intraoperative injection of perfluoropropane (C3F8) during fistulizing surgery has recently been advocated to maintain intraocular pressure in the immediate postoperative period following the insertion of a Molteno tube with a vicryl tie.1 We describe a patient who, following a trabeculectomy, underwent manipulation of intraocular pressure by the alteration of posture and by preventing potential side effects of hypotony.
