Abstract
The article reports the case of a 9-year-old boy who presented with fixed dilated pupil
secondary to areosol inhalation of nebulised ipratropium bromide. While a fixed dilated
pupil is an alarming sign, if it is caused by inhalation of ipratropium bromide the condition
will resolve, although it may take up to 24 hours. The differential diagnosis of anisocoria
includes partial third nerve palsy, tonic pupil, direct trauma to the eye and pharmacological
mydriasis. In some cases the diagnosis can be determined by using pilocarpine
eye drops. A unilateral dilated pupil can be a worrying sign that requiries thorough
investigation. This could occasionally be avoided if the benign differential diagnosis described
is considered.
