title: Effect of fronto-orbital advancement on astigmatism in patients with anterior plagiocephaly.
abstract: The purpose of this study was to determine the effect of unilateral fronto-orbital advancement (FOA) or bilateral FOA on ocular aspects of plagiocephaly. A retrospective review of ocular findings in 16 patients with plagiocephaly was performed. Patients were divided into 2 groups: 12 patients who underwent bilateral FOA (bFOA) and 4 patients who underwent unilateral FOA (uFOA), and ocular findings were compared. One-half of patients showed strabismus in both groups, and all had exotropia. Hypertropia was found only on the same side of the plagiocephaly in 17% of the bFOA group and 25% of the uFOA group. One-third of the patients in the bFOA group and one-half of patients in the uFOA group had oblique muscle dysfunction. In terms of astigmatism, the degree of with-the-rule astigmatism on the contralateral side was larger in the bFOA group compared to the uFOA group (p = 0.030). The degree of with-the-rule astigmatism was larger on the contralateral side than the ipsilateral side (p = 0.005) in the bFOA group. Patients with abnormalities in ductions/versions had larger astigmatism on the contralateral side than those without abnormalities in ductions/versions. In conclusion, bilateral FOA could induce unwanted outcomes of larger astigmatism on the contralateral side. Astigmatism should be carefully evaluated after bilateral FOA.
