The effect of multiple psychotropic drugs on the accommodation of pre-presbyopes.
Among 1,000 psychiatric patients in a Veterans Administration hospital, there were 15 in the age group 21--41 years who complained of difficulty at near and who showed reduced accommodation. All 15 were receiving benztropine mesylate (Cogentin) and most also received a phenothiazine or a butyrophenone. The reduction in accommodation ranged from 40 to 100%. Data are insufficient to correlate doses of specific drugs with the precise extent of the impairment of accommodation.
