Prevalence of refractive errors and ocular motility disorders in 5- to 10-year-old Swedish children born prematurely or at full-term.

Knowledge of the occurrence of visual and ocular problems in children is important when eye health care systems are designed. We have studied the prevalence of ocular changes in all children born prematurely during 1976-1981 in Stockholm county and compared the findings with those obtained in a random sample of full-term children from the same period and area.
