title: Persistent mydriasis following intravenous atropine in a neonate.
abstract: A neonate whose mother had recently taken amitriptyline developed fixed dilated pupils after a modest dose of intravenous atropine. Interaction of atropine with neonatal amitriptyline levels is suggested and evidence of neonatal effects from maternal antidepressant use is examined. There were no neurological sequelae, and the neonate's pupils became reactive again after 7 h.
