title: Ocular lesions in horses with lymphosarcoma: 21 cases (1977-1997).
abstract: OBJECTIVE
  To determine the most common ocular lesions in horses with lymphosarcoma.
  
  
  METHODS
  Retrospective study.
  
  
  METHODS
  79 horses histologically confirmed to have lymphosarcoma.
  
  
  METHODS
  Ophthalmic examinations were performed by a single individual.
  
  
  RESULTS
  21 of 79 horses had lesions involving the eye or ocular adnexa. Infiltration of the palpebral conjunctiva and eyelids was the most common lesion (n = 11). Other lesions included uveitis (n = 4), corneoscleral masses (2), third eyelid masses (2), and diffuse retrobulbar infiltrates (2).
  
  
  CONCLUSIONS
  In horses with lymphosarcoma, ocular lesions may precede or be more obvious than lymph node enlargement or signs of visceral involvement. Early recognition of ocular lesions suggestive of lymphosarcoma may allow a more rapid diagnosis of lymphosarcoma in horses.
