Amiodarone-induced corneal deposits.

L J Kaplan, W E Cappaert

    Annals of Ophthalmology
    |August 1, 1984
    PubMed
    Summary

    Amiodarone (Cordarone) can cause corneal deposits in patients treated for ventricular arrhythmias. These deposits are usually mild, reversible upon drug discontinuation, and rarely affect vision.

    Area of Science:

    • Cardiology
    • Ophthalmology
    • Pharmacology

    Background:

    • Amiodarone (Cordarone) is an antiarrhythmic drug investigated for treating ventricular arrhythmias.
    • Corneal deposits are a known side effect of amiodarone therapy.

    Purpose of the Study:

    • To investigate the occurrence, characteristics, and reversibility of corneal deposits associated with amiodarone treatment.
    • To correlate deposit severity with amiodarone dosage and treatment duration.

    Main Methods:

    • Observation of 27 patients undergoing amiodarone therapy since 1977.
    • Documentation of corneal deposit stages (mild, moderate, severe) in the corneal epithelium basal cell layer.
    • Monitoring of visual acuity and deposit regression after drug discontinuation.

    Main Results:

    • Corneal deposits were observed in 27 patients, correlating with amiodarone dosage and treatment duration.
    • Deposits were located in the corneal epithelium basal cell layer.
    • Vision impairment was rare; deposits regressed within weeks to 1.5 years after amiodarone cessation.

    Conclusions:

    • Amiodarone-induced corneal deposits are a common, dose-dependent side effect.
    • These deposits are typically reversible upon discontinuation of amiodarone.
    • Ophthalmological monitoring is advisable for patients on long-term amiodarone therapy.
