title: Cytomegalovirus retinitis in a patient with proliferative diabetes retinopathy.
abstract: OBJECTIVE
  To report a case of cytomegalovirus (CMV) retinitis in an immunocompetent patient with proliferative diabetic retinopathy (PDR).
  
  
  METHODS
  Case report.
  
  
  METHODS
  A 69-year-old man presented with a 44-year history of diabetes mellitus and 4 years of PDR. Fundus of left eye could not be visualized because of vitreous hemorrhage. Laboratory tests indicated normal immunological status.
  
  
  RESULTS
  Yellowish white retinal exudative lesion and whitening inside vascular arcades were observed during vitrectomy. Multiplex PCR using vitreous sample detected CMV DNA at 4.37 × 10(4) copies/mL. CMV retinitis was diagnosed.
  
  
  CONCLUSIONS
  If atypical findings of PDR are observed, a multiplex PCR test should be performed for further investigation.
