Abstract
OBJECTIVE
To report clinical findings after accidental ocular instillation of Angel's trumpet (Datura suaveolens) sap.
METHODS
A 24-year-old man, with no particular past history, presented with sudden-onset of unilateral mydriasis. The clinical appearance, as well as the detailed history, made possible the etiologic diagnosis of ocular exposure to sap from Angel's trumpet, a plant containing natural alkaloids with parasympatholytic properties.
CONCLUSIONS
A toxic etiology of sudden-onset anisocoria may be established by taking a detailed history and being familiar with possible causative agents. Accidental ocular instillation of sap from Angel's trumpet should be noted as a possible cause of sudden-onset mydriasis and/or systemic symptoms such as tachycardia in otherwise healthy patients.
