Eskimos do seem to have shallower ACs than do other racial groups. Measurements of the AC angle seem to decline more rapidly over life among Eskimos than among blacks or whites, a phenomenon also observed by us among Chinese, another group with high ACG prevalence. This apparent more rapid decline may be due to a cohort effect with higher prevalence of myopia and resulting wider angles among younger Eskimos and Chinese.

Approximately 3.6 million persons in the United States are infected with the hepatitis C virus (HCV), a condition with both hepatic and extrahepatic sequelae. Although no pathognomonic manifestation of HCV infection in the eye has been demonstrated, associations between HCV infection and various ocular syndromes have been reported in small case series and individual patients. At this time, the ocular manifestations of HCV infections best supported by the literature include a dry eye syndrome similar to Sjögren syndrome, and ischemic retinopathy caused by either an HCV-induced vasculitis or treatment with interferon. Patients with diabetes seem to be more susceptible to interferon retinopathy and to subsequent permanent visual loss. There have been no cases of HCV transmission via corneal transplantation, suggesting that current cadaveric screening protocols are effective in preventing this route of transmission. Screening for HCV should be considered in patients with risk factors for HCV infection who suffer from unexplained ischemic retinopathy or dry eyes.

We describe a case of severe visual loss as a result of West Nile virus (WNV) infection. Associated headache and fever led to the proper diagnosis and management, but the findings of optic neuritis, retinitis, and uveitis were a surprising and prominent component of the patient's meningitis syndrome. Physicians diagnosing and treating patients with WNV infection should be alerted to the possibility of ocular and optic nerve involvement, which may leave permanent neuropathic residua.
