Purpose of reviewDilated 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.Recent findingsThe 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.SummaryThe 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.
