Loss of vision due to eye metastasis is generally uncommon, representing an ophthalmological diagnostic and therapeutic challenge. We here report a case of a smoker patient finally diagnosed with lung cancer, whose initial symptom was visual loss due to choroidal metastasis. Given that the majority of subjects presenting with uveal metastasis have already developed other distant metastases as well, a complete diagnostic work-up of these patients is always required. Despite being rare, eye metastasis from a lung malignancy should always be suspected in smokers presenting with progressive vision deterioration.
