PURPOSE
To report clinical findings after accidental ocular instillation of Angel's trumpet (Datura suaveolens) sap.
OBSERVATION
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.
DISCUSSION
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.
目的
报告曼陀罗（洋金花）汁液意外滴入眼内后的临床发现。
观察结果
一名24岁男性，无特殊既往史，出现单侧瞳孔突然散大。临床症状及详细病史使得眼部接触曼陀罗汁液的病因诊断成为可能，曼陀罗是一种含有具有抗副交感神经特性天然生物碱的植物。
讨论
通过详细询问病史并熟悉可能的致病因素，可确定突发不等大瞳孔的中毒病因。应注意，在其他方面健康的患者中，意外将曼陀罗汁液滴入眼内可能是突发瞳孔散大及/或心动过速等全身症状的一个原因。
