title: High-frequency ultrasound of anterior segment retinoblastoma.
abstract: OBJECTIVE
  To evaluate anterior segment retinoblastoma with high-frequency ultrasound.
  
  
  METHODS
  Interventional case report.
  
  
  METHODS
  An 11-year-old boy with a total retinal detachment and multiple white anterior chamber nodules was examined with high-frequency ultrasound before enucleation of the globe.
  
  
  RESULTS
  Multiple solid and cystic nodular tumors were found in the anterior chamber angle. With high-frequency ultrasound, tumor was discovered posterior to the iris, over the ciliary processes, and on the lens capsule. No calcifications were noted. Other findings included angle closure related to iris neovascularization and uveal thickening.
  
  
  CONCLUSIONS
  High-frequency ultrasound can be used to evaluate retinoblastoma extension into the anterior segment. These images may be used for comparison in future cases of retinoblastoma with anterior chamber invasion.
