Methadone and Infant Vision

Drug-addicted pregnant women are often given methadone, a heroin substitute, during their pregnancy; it’s associated with a “reduced incidence of both intrauterine growth restriction and preterm birth compared with non-treated heroin addicts.” New evidence, however, shows that methadone may cause vision problems in children exposed in utero, and infants who experience severe methadone withdrawal post-birth are particularly prone to vision problems.[%comments]
