title: Idiopathic sclerosing orbital inflammation--a case series study.
abstract: OBJECTIVE
  It was the aim of this study to perform a review of the clinical features, treatments and outcomes of patients with idiopathic sclerosing orbital inflammation (ISOI) in Taiwan.
  
  
  METHODS
  All patients with histologically confirmed ISOI from 1995 to 2007 at the National Taiwan University Hospital were included. We reviewed the medical charts to see the clinical presentation, treatment modalities, treatment efficacy and final clinical status of these patients.
  
  
  RESULTS
  Six male and 3 female patients ranging in age from 33 to 82 years were included. The most common symptoms were pain and blurred vision (both 77.8%). Reduced visual acuity and proptosis were the most common signs (both 89%). Five patients received oral steroid treatment with/without pulse therapy combined with tissue removal, the response to which was good in 1 patient and partially effective in the other 4 patients. One patient received oral steroids and surgery, followed by radiotherapy, with only partial response. Patients with oral prednisolone or surgery only all had poor responses.
  
  
  CONCLUSIONS
  ISOI is rare and also difficult to diagnose and manage. Early intervention with steroids/immunosuppressants combined with surgical debulking procedures may result in control or regression of this recalcitrant disease.
