Background and aims  Although an increasing number of children are born to mothers in opioid maintenance therapy ( OMT ), little is known about the long‐term effects of these opioids. Previous studies suggest an association between prenatal  OMT  exposure and difficulties in eye movement control. Also, the effects of tobacco smoking on eye movements have been reported. The present study examined the influence of eye movements, i.e. smooth pursuit, on visuomotor capabilities in children of smoking mothers in  OMT .    Design  The study comprised a 2 ( OMT  versus contrast group) × 2 (slow versus fast smooth pursuit) between‐subject factorial design.    Setting  The cognitive developmental research unit at the  U niversity of  O slo,  N orway.    Participants  Participants were 26 4‐year‐old children of tobacco‐smoking women in  OMT  and 23 non‐exposed 4‐year‐old children, with non‐smoking mothers, matched by gender and age.    Measurement  Eye movements and smooth pursuit were recorded using a  T obii 1750 eyetracker. Visuomotor functions were examined by  B ender test.    Findings  The  OMT  group tracked slowly moving objects with smooth pursuit in a similar manner to their non‐exposed peers. When fast smooth pursuit was measured, the  OMT  group of children tracked the object more slowly than the contrast group,  P  = 0.02,  η p    2   = 0.11. A regression analysis showed that fast smooth pursuit predicted children's performance on a visuomotor task,   R  2   = 0.37.    Conclusion  Impaired eye‐tracking skills in 4‐year‐old children exposed to methadone or buprenorphine and tobacco prenatally could inhibit the development of some cognitive functions in later life.
