title: [Ocular metastases heralding non-small cell lung cancer: two cases].
abstract: BACKGROUND
  Ocular metastases are rare in patients with lung cancer, and exceptionally indicate the condition.
  
  
  METHODS
  We report 2 patients with symptomatic ocular metastases indicating lung adenocarcinoma, involving the choroid in the first case and the optic disc in the other, associated with other metastases. No improvement of visual acuity was observed after chemotherapy and radiotherapy.
  
  
  CONCLUSIONS
  Ocular metastases may indicate lung cancer, and are usually associated with other metastatic sites. The global prognosis is poor but an early treatment should result in improvement of visual prognosis.
