title: Blurred vision due to choroidal metastasis as the first manifestation of lung cancer: a case report.
abstract: BACKGROUND
  Reduction in visual acuity combined with blurred vision is rarely the first sign of lung cancer and very few cases have been announced globally.
  
  
  METHODS
  A case of a 46-year-old man who admitted with blurred vision is presented. His medical history, apart from a mild gastritis under treatment was negative. Ocular examination revealed a decrease in visual acuity due to a choroidal tumor. Further image body scans demonstrated a right lung lesion with dissemination to other organs. Diagnosis of a non-small cell lung cancer established after a VATS biopsy carried out.
  
  
  CONCLUSIONS
  Blurred vision due to choroidal metastasis as the primary symptom of lung cancer is very uncommon. A great index of suspicion is essential when a choroidal lesion appears.
