Abstract

Purpose: To report a case of unilateral pharmacologic mydriasis following accidental ocular exposure to tiotropium bromide.
Methods: A 35-year-old male presented with diminished near vision in the right eye. Examination revealed a dilated, non-reactive pupil in the affected eye with otherwise normal ocular findings. There was no history of any topical or oral medication. After a detailed history, it was found that he works in a paint factory. Imaging studies were unremarkable. After a detailed examination, it was found that he was exposed to tiotropium bromide.
Results: A diagnosis of pharmacologic mydriasis was made, and the patient was managed conservatively.
Conclusion: Accidental ocular exposure to tiotropium bromide can cause transient unilateral mydriasis. Awareness of this condition is important to avoid unnecessary investigations and ensure appropriate management.
