Abstract
The Ahmed valves are one of the aqueous drainage devices used for glaucoma treatment. It has a venturi type valve that permits the drainage of the aqueous to the equatorial orbital space across a limbal shunt. The echographic characteristics of other valves have been described. We studied 24 patients with this implant, and describe the echographic characteristics at 4 weeks after surgery. We found that 33% had a large filtering bleb, 45% had a moderate filtering bleb and 12.5% had a small filtering bleb. The echographic characteristics are similar to those described previously.
