Accidental mydriasis from exposure to Angel's trumpet (Datura suaveolens).
OBJECTIVE
To report clinical findings after accidental instillation into the eye of sap from Angel's trumpet (Datura suaveolens).


METHODS
We report findings on seven patients who developed sudden onset of unilateral mydriasis. At least three of them also had ipsilateral cycloplegia and one developed transient tachycardia.


RESULTS
The symptoms evolved after ocular exposure to sap from Angel's trumpet, a plant containing natural alkaloids with parasympatholytic properties. Six patients were initially unaware of the cause of their symptoms. In these cases, patient history revealed recent contact with Angel's trumpet.


CONCLUSIONS
Accidental ocular instillation of sap from Angel's trumpet should be noted as a cause of sudden onset of mydriasis in otherwise unaffected patients and also of general symptoms like tachycardia.
