Amblyogenic anisometropia in the contralateral eye in unicoronal craniosynostosis.

摘要

PURPOSE: To describe the prevalence and nature of anisometropic refractive errors in children with unilateral coronal craniosynostosis. METHODS: Retrospective chart review of children with unilateral coronal craniosynostosis who underwent ophthalmic evaluation, including refraction. RESULTS: Refraction was available for 25 of 61 children with unilateral coronal craniosynostosis. Of the 25, 56% had amblyogenic anisometropia. Of these, 79% had the greater refractive error contralateral to the coronal synostosis, mostly (91%) consisting of greater with-the-rule astigmatism in the contralateral eye. Seventy-two percent of Hispanic children had amblyogenic anisometropia, compared with only 14% of non-Hispanic children (p= 0.02). Although Hispanic children tended to receive both surgery and ophthalmic evaluation at older ages than non-Hispanic children, these factors did not appear to account for the difference between ethnicities. There was no detectable association between anisometropia and the timing of fronto-orbital advancement surgery. CONCLUSIONS: Children with unilateral coronal craniosynostosis are at increased risk of developing amblyogenic levels of anisometropia in the eye contralateral to the synostosis and require early evaluation and refraction even in the absence of strabismus.
