INTRODUCTION: The metastases of lung cancer to bilateral choroids symmetrically and simultaneously are very rare. Almost all patients with choroid metastasis can be treated with external beam radiotherapy in order to increase quality of life and preserve vision. MATERIAL AND METHODS: We documented a case and studied the effect of icotinib on choroidal metastases in bilateral eyes simultaneously from pulmonary adenocarcinoma. RESULTS: A 49-year-old Chinese man presented with bilateral vision losing simultaneously for 4 weeks, it was as an initial presentation in the clinical. The examinations with ophthalmofundoscopy, ultrasonography, and fluorescein angiography showed the lesions in bilateral choroids, two solitary juxtapapillary yellow-white choroidal metastases inferior to the optic discs with bleeding. Positron emission tomography confirmed the choroidal metastases and further proved that it was from lung cancer with lymph nodes and multiple bone metastasis. The biopsy taken from the lung by bronchoscopy and needle biopsy from supraclavicular lymph nodes revealed the pulmonary adenocarcinoma with epithelial growth factor receptor mutation (exon 21). The patient was treated with oral icotinib (125 mg, three times a day, TID). Five days after starting icotinib therapy, the patient's visions were rapidly recovered. Two months after the treatment with icotinib, the choroidal metastases regressed to small lesions, and the visions were preserved to before. The lung tumor and oth...
