PURPOSE: To report a case of bilateral regression of choroidal metastasis with adenocarcinoma of the lung treated with gefitinib. METHODS: Retrospective case review of a 68-year-old woman with pulmonary adenocarcinoma with choroidal metastasis who presented with visual loss in the left eye as the initial manifestation. Her visual acuity was 6/6 in the right eye and 6/60 in the left eye before the start of gefitinib administration. Best-corrected visual acuity and spectral-domain optical coherence tomography were compared between baseline and 3 months after treatment. RESULTS: Best-corrected visual acuity in the left eye had improved to 6/30 3 months after oral gefitinib. The elevated lesions of the right eye disappeared, with decrease of subretinal fluid and retinal pigment epithelial atrophy. Spectral-domain optical coherence tomography showed that subretinal fluid of the left eye was also reduced. CONCLUSIONS: Oral gefitinib could be effective for regression of choroidal metastasis in patients with adenocarcinoma of the lung and provides a potential treatment option.
