Abstract

A 25-year-old man with a variety of unusual ocular symptoms was fully investigated and no abnormality discovered. The suspicion of self-medication with a mydriatic was confirmed when homatropine was isolated in his tears. We describe a method for collecting tears which allowed biochemical confirmation at leisure.
