title: Pulmonary tuberculosis associated retinal vasculitis presenting as xanthopsia.
abstract: OBJECTIVE
  To report a patient presenting with unilateral xanthopsia who was diagnosed as having retinal vasculitis with pulmonary tuberculosis.
  
  
  METHODS
  A case report.
  
  
  METHODS
  A 20-year-old man presented with xanthopsia in the right eye. Fundus examination revealed multiple retinal hemorrhages, vascular sheathing, and a yellowish retina.
  
  
  RESULTS
  He was diagnosed as having retinal phlebitis with pulmonary tuberculosis by chest x-ray and computerized tomography scans and treated with anti-tuberculosis medications. After treatment, he described clearance of xanthopsia, and fundus examination also showed normal coloration.
  
  
  CONCLUSIONS
  Xanthopsia may be a sign of retinal vasculitis associated with tuberculosis. Ophthalmologists should suspect retinal vasculitis when patient complains of xanthopsia.
