Clonazepam-induced acute bilateral transient myopia

Abstract

Clonazepam belongs to the benzodiazepine group of drugs and has a quick onset and prolonged duration of action. It is frequently prescribed for treatment of anxiety disorder and panic attacks. Benzodiazepines are known to induce angle closure glaucoma in susceptible eyes but acute drug induced myopia is reported only with Chlordiazepoxide usage. We report the case of a 45-year-old woman who developed acute bilateral myopia after consumption of clonazepam which resolved completely after drug withdrawal.
