A 12-year-old boy was brought to the emergency department by his parents with new-onset anisocoria. He complained of blurry vision and of his left pupil being larger than the right. His visual acuity was normal and examination revealed a painless left mydriasis. A thorough history and targeted examination yielded the diagnosis of pharmacologic mydriasis caused by ocular exposure to Angel's Trumpet (Datura suaveolens), a plant containing toxic alkaloids with anti-cholinergic properties. The patient and his family were spared expensive and time-consuming tests (e.g., magnetic resonance imaging) or further referral. His symptoms resolved spontaneously in 3 days.
一名12岁男孩被父母带到急诊科,出现新发的瞳孔不等大。他诉说视力模糊,并且左瞳孔比右瞳孔大。他的视力正常,检查发现左侧无痛性瞳孔散大。详细的病史询问和针对性检查得出诊断,是眼部接触曼陀罗(光滑曼陀罗)导致的药物性瞳孔散大,曼陀罗是一种含有具有抗胆碱特性的有毒生物碱的植物。患者及其家人避免了进行昂贵且耗时的检查(如磁共振成像)或进一步转诊。他的症状在3天内自行缓解。
