Choroidal metastasis as a presenting feature in a metastatic lung carcinoma

We report a case of a 65-year-old female who presented to us with diminution of vision in the right eye. She was only able to perceive light in the right eye, and the left eye had a vision of 20/20, N6. Anterior segment examination in both eyes was unremarkable except for senile cataract in the left eye. Posterior segment examination revealed features of choroidal metastasis in both eyes and exudative retinal detachment in the right eye. Multimodal imaging helped in the further confirmation of metastatic lesions. Right-eye fundus autofluorescence showed hyperautofluorescent lesions, ultrasound B-scan showed an elevated mass lesion in the choroid with moderate to high internal echogenicity, and optical coherence tomography showed a lumpy-bumpy appearance of the retinal pigment epithelium as well as an elevated choroidal mass lesion beneath it. On detailed systemic evaluation, the primary site of cancer was found to be the lungs. The patient was referred to a pulmonologist and an oncologist for chemotherapy and further management.
