Abstract
BACKGROUND: Pfeiffer syndrome is a rare, genetic condition characterized by craniosynostosis and midface hypoplasia, with resultant ophthalmic sequelae. The gold standard of treatment is fronto-orbital advancement. We analyzed a large database of Pfeiffer syndrome patients to report the rate of ophthalmic sequelae and the long-term visual outcomes after craniofacial surgery and to compare Pfeiffer syndrome to other craniosynostosis syndromes. METHODS: The medical records of Pfeiffer syndrome patients examined between 1988 and 2010 were examined retrospectively. Diagnosis was based on clinical and genetic testing. Long-term data were presented as a rate of incidence per person-year to overcome variable follow-up times. RESULTS: A total of 22 patients were included. Proptosis (n = 21 [95%]), refractive error (n = 13 [59%]), and strabismus (n = 12 [55%]) were the most common primary features at presentation. Exposure keratitis (n = 9 [41%]) and amblyopia (n = 3 [14%]) were the most common secondary features. At presentation, 24 eyes [86%] with documented best-corrected visual acuity were normal; 4 [14%] were impaired; and none were blind. Fronto-orbital advancement reduced the rate of proptosis from 28%/person-year at presentation to 2%/person-year. There were no cases of active exposure disease postoperatively. At last follow-up, there was a 7%/person-year rate of impaired vision secondary to corneal scarring and amblyopia and a 3%/person-year rate of blindness-all from optic atrophy. CONCLUSIONS: In this study, the rates of proptosis and exposure keratitis were high in Pfeiffer syndrome, especially compared to Apert and Crouzon syndromes. Fronto-orbital advancement was successful in correcting orbital abnormalities. Long-term ophthalmic follow-up is essential to ensure best visual outcome. Crown
