[Pupillary disorder after use of asthma spray aerosol].

A 46-year-old patient was referred as an emergency case to our neuro-ophthalmologic department, because her left pupil was mydriatic and unreactive since the morning of the same day. This pupil did not constrict normally on application of 1 % pilocarpin eye drops. Thus the diagnosis of a medication-induced mydriasis was established. The causative agent proved to be an aerosol, containing ipratropium bromide used for asthma treatment.
