title: Coats-type retinitis pigmentosa in a 4-year-old child.
abstract: OBJECTIVE
  To describe the occurrence of Coats-like exudative retinopathy secondary to underlying retinitis pigmentosa in a 4-year-old child.
  
  
  METHODS
  Case report.
  
  
  RESULTS
  A 4-year-old girl had bilateral exudative retinal telangiectasia requiring photocoagulation. She subsequently developed progressive nyctalopia, photophobia, and reduced peripheral vision. Electroretinography and dark adaptometry at age 8 years confirmed the diagnosis of retinitis pigmentosa.
  
  
  CONCLUSIONS
  Coats-like exudative retinopathy secondary to retinitis pigmentosa can manifest as early as age 4 years and can precede the diagnosis of the underlying retinal dystrophy.
