Dilated pupil is a diagnostic challenge encountered by neurologists and ophthalmologists. The aim of this review is to provide an overview of the current data and guidelines concerning dilated pupils.
The majority of recent reports on dilated pupils are indicative of several medical conditions that require evaluation. The topical synthetic parasympatholytic agents; local contamination of antihistamines with their antimuscarinic effects; atropine, scopolamine, and tropane alkaloids in all species of Datura plants may produce mydriasis.
The causes of pupillary dilatation can be unilateral, bilateral, and transient. The clinical approach to dilated pupils requires stepwise evaluation, and based on the findings, unnecessary and costly procedures can be avoided.
瞳孔散大是神经科医生和眼科医生遇到的诊断难题。本文旨在综述目前有关瞳孔散大的相关数据和指南。
近期有关瞳孔散大的多数报道均表明存在多种需要评估的疾病。局部应用拟副交感神经药物；局部应用具有抗胆碱能作用的抗组胺药物；所有曼陀罗植物中的阿托品、东莨菪碱和托烷生物碱均可导致瞳孔散大。
瞳孔散大的原因可能是单侧、双侧和一过性的。瞳孔散大的临床评估需要逐步进行，根据检查结果，可以避免不必要的和昂贵的检查。
