Abstract
Purpose: To report a possible association between interferon alfa therapy and anterior ischemic optic neuropathy (AION).
Design: Database study and review of the literature.
Participants: 36 case reports from spontaneous reporting systems and from the literature.
Methods: Case reports from a review of the literature were combined with spontaneous reports from the National Registry of Drug-Induced Ocular Side Effects, the World Health Organization (WHO), and the Food and Drug Administration (FDA) looking for reports on interferon therapy associated with optic neuropathy.
Main Outcome Measures: Data garnered from the spontaneous reports include the type of interferon, age, gender, adverse drug reaction (ADR), dosage, duration of therapy until onset of ADR, concomitant drugs, other systemic disease, dechallenge and rechallenge data.
Results: Thirty-six case reports of AION are described in association with interferon alfa therapy. Average age was 54 ½ years with 26 males and 10 females. Median duration of therapy to onset of AION was 4 ½ months with 50% of subjects suffering some form of permanent vision loss. AION was bilateral in 67% of subjects. There are 3...
