title: Intraocular infiltration of adult T-cell leukemia.
abstract: OBJECTIVE
  To report a case of adult T-cell leukemia (ATL) with unilateral dense vitreous opacities that benefited from vitrectomy.
  
  
  METHODS
  Interventional case report.
  
  
  METHODS
  Diagnostic vitrectomy was performed on a 59-year-old man with ATL who had vitreous opacity in the right eye.
  
  
  RESULTS
  White infiltration of the retina was noted after vitrectomy. Cytologic examination of the vitreous specimen obtained during surgery revealed infiltration of ATL cells into the vitreous and retina. After vitrectomy and additional chemotherapy, visual acuity improved in the right eye from 20/100 to 25/20.
  
  
  CONCLUSIONS
  Infiltration of the vitreous and retina by ATL is rare. Diagnostic vitrectomy is effective for treatment and visual improvement.
