Shallow anterior chamber occasionally is a sequel of cataract extraction. It is of two types. In one, the chamber simply does not reform after operation and a gross leak of aqueous generally can be demonstrated. In the other, commoner type, the anterior chamber does reform, but it decreases in volume a few days or even two to three weeks after operation. This report primarily concerns the second type. The clinical picture is usually described as a triad of findings, consisting of shallow anterior chamber, hypotony, and choroidal detachment; however, this picture is not constant. The choroidal detachment usually antedates and outlasts the shallow chamber. In fact, a large choroidal detachment may develop without detectable alteration of the anterior segment. The shallow anterior chamber usually deepens spontaneously within a few days, but it may persist for weeks. Its persistence is considered significant because.it favors the formation of anterior synechiae and secondary
