[Preliminary study of the topical use of thymoxamine]

In this work the Authors have tried to show the efficacy of TMX, as a miotic drug, and to find out the lowest concentration which can give the best results with the minor complications. Seven patients, in whom TMX was instilled in both eyes at 0.50%, 1%, 2% concentrations, were studied. A mydriatic was instilled before in the right eye, in order to obtain mydriasis whereas the left eye served as control. The 0.5% concentration was as efficacious as 1% and 2% ones, but had less side-effects.
