title: Excision of periorbital hemangiomas to correct visual abnormalities.
abstract: OBJECTIVE
  To determine whether early surgical excision of complicated periorbital hemangiomas (CPHs) reversed refractive errors and prevented further visual complications; CPHs can cause visual complications including astigmatism, strabismus, and occlusion of the visual axis with resultant amblyopia.
  
  
  METHODS
  Retrospective review of patient series from a tertiary care pediatric referral center. Nine patients with CPHs were managed by otolaryngology and ophthalmology services with complete surgical excision. Preoperative eye examination findings were compared with postoperative findings.
  
  
  RESULTS
  Comparison of preoperative and postoperative refraction measurements and/or eye examination findings indicated reduction of astigmatism and substantial improvement in vision as measured by refractive changes and reduction of pupillary occlusion.
  
  
  CONCLUSIONS
  Total excision of CPHs is a safe and effective approach. When completed early, excision provides definitive therapy, reduces or eliminates astigmatism, and can prevent amblyopia in pediatric patients when pupillary occlusion is present.
