Adverse ocular effects of flecainide

PURPOSE: To study if flecainide has ocular adverse effects. METHODS: Both eyes of 38 flecainide medicated patients were thoroughly examined including colour vision, contrast sensitivity and visual fields. RESULTS: 10.5% of the patients had blurred vision on lateral gaze lasting for a couple of seconds. Small corneal deposits were found in 14.5% of the patients. All visual function tests were normal. CONCLUSION: Flecainide seems to be a safe drug with minimal ocular adverse effects.
