The effect of stimulant medication on recognition memory was examined in 18 children with attention-deficit/hyperactivity disorder (ADHD). Recognition memory was assessed using a delayed matching-to-sample task at 6 delays ranging from 1 to 32 s. Each child was tested on 2 separate occasions, once 60 to 90 min after taking stimulant medication and the other at least 18 hr after taking medication. Children performed significantly better on medication than off. Stimulant administration significantly increased accuracy and the number of nickel reinforcers earned. Decreases in observing response latency and correct choice response latency occurred after taking stimulant medication. The results indicate that stimulant medication improved recognition memory for children with ADHD.

Abstract. A 68-year-old man was noted to have an anterior chamber mass shortly after uneventful cataract surgery. The mass was believed to be iatrogenic in nature and necessitated surgical removal because of intermittent obstruction of vision. The patient was observed closely and achieved a good visual outcome with no complaints. This case is described to illustrate a potential hazard of modern clear cornea cataract surgery.
