The study of Danish researchers suggests that each additional cigarette a pregnant woman smokes per day on average, increases the risk of strabismus in children for about 5% … The negative impact of smoking in pregnancy was further pronounced when the patients were smoking at an advanced pregnancy, warn researchers from the Statens Serum Institute in Copenhagen.
According to them, strabismus affects 2 to 3% of children.
Some types of strabismus are associated with difficulties in the functioning of muscles, and some with nerve damage.
If not corrected, strabismus can lead to progressive irreversible loss of vision, reported the American Journal of Epidemiology.
Some earlier studies have already indicated an association between alcohol consumption during pregnancy and a higher risk of strabismus in children.
According to new data collected from 1300 mothers of children with strabismus, smoking during pregnancy increased the risk of strabismus by an average of 26%.
