Objective: To examine the relationship between neonatal, periventricular brain damage and visuomotor performance in extremely-low-birthweight (ELBW) children of normal intelligence whose birthweights were appropriate for gestational age (AGA).

Methods: Seventy-eight ELBW and 23 control children, all six years of age, completed two "motor-free" tests of visual spatial ability and three tests requiring visuomotor control.

Results: Full-term control children outperformed ELBW children with periventricular brain damage on all three tests requiring visuomotor guidance. No group differences were found on two "motor-free" tests of visual spatial ability. ELBW children without periventricular brain damage performed in a manner indistinguishable from controls on all tests included in this study.

Conclusions: The findings indicate that the presence and severity of periventricular brain injury are important factors to consider in predicting visuomotor development in ELBW children.

Key words: prematurity; extremely low birthweight; visuomotor; periventricular brain damage; intraventricular hemorrhage; visual; outcome.
