Insights
Pfeiffer syndrome patients frequently experience ophthalmic issues like proptosis and keratitis. Fronto-orbital advancement surgery effectively corrects these, but long-term vision monitoring is crucial for optimal outcomes in craniosynostosis patients.
Area of Science:
- Ophthalmology
- Genetics
- Craniofacial Surgery
Background:
- Pfeiffer syndrome is a rare genetic disorder causing craniosynostosis and midface hypoplasia, leading to ophthalmic complications.
- Ophthalmic sequelae are common in Pfeiffer syndrome, necessitating effective surgical and long-term management strategies.
Purpose of the Study:
- To analyze ophthalmic sequelae rates in Pfeiffer syndrome patients.
- To evaluate long-term visual outcomes following fronto-orbital advancement surgery.
- To compare ophthalmic findings in Pfeiffer syndrome to other craniosynostosis syndromes.
Main Methods:
- Retrospective analysis of medical records from 1988-2010 for Pfeiffer syndrome patients.
- Diagnosis confirmed via clinical and genetic testing.
- Long-term data presented as incidence rates per person-year.
Main Results:
- Proptosis, refractive error, and strabismus were primary features; exposure keratitis and amblyopia were common secondary issues.
- Fronto-orbital advancement significantly reduced proptosis rates and eliminated active exposure disease post-operatively.
- Long-term follow-up revealed vision impairment from corneal scarring/amblyopia and blindness from optic atrophy.
Conclusions:
- Pfeiffer syndrome presents high rates of proptosis and exposure keratitis, exceeding those in Apert and Crouzon syndromes.
- Fronto-orbital advancement is effective in correcting orbital abnormalities associated with Pfeiffer syndrome.
- Essential long-term ophthalmic follow-up is required to ensure the best possible visual outcomes for patients.
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.
