In 18 patients, 2% pilocarpine, 2% pilocarpine plus tropicamide 10:1, and 2% aceclidine were tested with respect to the degree of spasm of accommodation induced by these drugs. Aceclidine had the least effect on accommodation, making it the recommended drug for use in patients with glaucoma and considerable remaining accommodation, i.e., most patients under the age of 50 years.
