When surgery is indicated in the management of glaucoma, the cyclodialysis operation provides an internal drainage mechanism which is thought by some to resemble most closely the physiologic state.1 However, failure of the cleft to remain patent sometimes leads to an unsuccessful operation. In the past, foreign materials of many types,2-4 magnesium, gold, platinum, stainless steel, etc., have been advocated as implants to keep the cleft open, but generally these have caused undue amounts of inflammatory reaction. The ideal substance to maintain patency of the cleft should be nonantigenic and should not give rise to severe inflammatory reaction; it should be absorbable but should be absorbed slowly enough to keep the cleft open while the postoperative reaction and hyphema subside. Except for its rather rapid absorption, an air bubble fulfills these requirements.5 However, in cases where fibrosis is more marked postoperatively an air bubble is often inadequate.
