title: [Analysis of misdiagnostic causes of Coats disease].
abstract: OBJECTIVE
  To analyze the clinical features and misdiagnostic causes of Coats disease.
  
  
  METHODS
  The clinical data were retrospectively analyzed in 69 eyes of 68 patients with Coats disease.
  
  
  RESULTS
  Misdiagnostic histories to a varying degree occurred in 11 of the 68 cases with a misdiagnosis rate of 16.18% and misdiagnostic mean time of 7.5 months.
  
  
  CONCLUSIONS
  Lack of knowledge on pathogenic characteristics of Coats disease, lack of typical manifestations, no timely accessory examinations, and advanced cases are the main causes of misdiagnosis.
