title: Retinal detachment associated with type III retinoblastoma regression after cryotherapy and external-beam radiotherapy.
abstract: OBJECTIVE
  To report a child with rhegmatogenous retinal detachment originating from a focus of type III retinoblastoma regression after cryotherapy and external-beam radiation therapy.
  
  
  METHODS
  Retinal detachment and multiple retinal holes, which were closely associated with the calcified mass of the regressed retinoblastoma, were treated with cryotherapy and scleral buckle.
  
  
  RESULTS
  Positioning the regressed tumor and the retinal holes on the scleral buckle closed the holes. Subretinal fluid gradually reabsorbed after surgery, and complete retinal reattachment resulted.
  
  
  CONCLUSIONS
  Rhegmatogenous retinal detachment is rare in patients with retinoblastoma, and scleral buckle can successfully manage such cases. In our patient, the detachment probably resulted from retinal necrosis secondary to cryotherapy and external-beam radiation therapy.
