Although lung cancer is a common cause of choroidal metastasis, choroidal metastasis is seldom encountered in medical clinical practice. We present a 67-year-old female patient with non-small cell lung cancer that initially manifested as choroidal metastasis. The patient received 2 cycles of gemcitabine and cisplatin, but the disease progressed. The chemotherapy regimen was changed to docetaxel for 4 cycles, and a partial response was achieved. Fourteen months after the diagnosis of lung cancer, the patient was mentally alert with fair activity, but blind in the right eye.
