Developmental coordination disorder (DCD) occurs in a small number of children who present with impaired body/eye coordination. No study of ophthalmic function in DCD exists despite vision’s primary role in perception. Ocular performance was therefore assessed with a battery of tests. Five hundred children aged between 5 and 7 years were involved in the study. Diagnosis of DCD was confirmed for 29 children by the Movement Assessment Battery for Children (ABC); 29 control children were randomly selected. Comprehensive examination with a battery of ophthalmic tests did not reveal any significant difference in visual status between the two groups. Strabismus was found in 5 children from both groups. All 5 children with strabismus from the DCD group showed a similar movement profile with the Motor Competence Checklist. While a causal relationship cannot be discounted, the presence of strabismus appears more likely to be a “hard” neurological sign of central damage common to this group. The evidence seems to indicate that a simple ophthalmic difficulty does not explain problems with movement control.
