Objective: to investigate visual function pre- and post surgery in children with single-suture non-syndromic craniosynostosis
Design: Twenty-nine infants (12 with sagittal synostosis, 10 with trigonocephaly and 7 with anterior plagiocephaly) were longitudinally evaluated using a battery of tests assessing various aspects of visual function, including ocular behaviour, acuity, visual fields and fixation shift. All infants were assessed before surgery and 2, 6 and 12 months after surgery.
Results: Before surgery only 16% of infants had completely normal visual function, while on the assessment performed 12 months after surgery, the number with normal results on all the tests increased to 65%. The only abnormalities found 12 months after surgical correction were mainly found on abnormal oculomotor behaviour in infants with plagiocephaly.
Conclusion: Abnormalities of visual function were not frequent in infants with non-syndromic craniosynostosis who underwent surgical correction. Approximately half of the patients had some visual abnormalities before surgery, which subsequently improved, showing a delayed visual maturation rather than persistent abnormalities.
