PURPOSE: To report a case of bilateral nonarteritic anterior ischemic optic neuropathy (NAION) in a hepatitis C (HCV) infected patient and demonstrate the relationship between HCV and the development of NAION.
METHODS: Case report.
RESULTS: A 43-year-old woman with chronic HCV infection and long-term euthyroid autoimmune thyroiditis suddenly lost vision in her right eye, and 6 months later in her left eye, due to NAION. Slightly elevated levels of aminotransferases suggested liver infection activity. Anti-HCV antibody was detected; the genotype of the virus was 1b and the viral RNA level was 1.8 x 106 IU/mL. Liver biopsy proved chronic active hepatitis (Ishak score grading: 7, staging: 2). Except for the elevated levels of antithyroid antibodies and a weak antinuclear factor, the detailed laboratory examinations (thrombophilia, cryoglobulin, anticardiolipin antibodies, co-infections) revealed no other abnormalities; a causative relationship between the underlying chronic hepatitis C and bilateral NAION therefore seems probable. The patient was treated with pegylated interferon and ribavirin for 1 year and a sustained viral remission could be achieved. Her vision has neither improved nor deteriorated further.
CONCLUSIONS: This appears to be the first reported case of bilateral NAION presumably caused by HCV infection.
