Intraocular metastasis is most commonly found within the choroid because of its luxurious blood supply, whereas metastasis to the retina, from a separate blood supply, is very rare. We report a rare case of synchronous metastases from lung carcinoma to the choroid of the right eye and the retina of the left eye and a complaint of low vision in the right eye.Methods:
We report a 63-year-old woman with progressive reduction of vision in her right eye for 1 year without previous history of cancer. The patient underwent comprehensive ophthalmic examination that included a multimodal evaluation: near-infrared reflectance scanning laser ophthalmoscopy, blue autofluorescence, and enhanced-depth imaging spectral domain optical coherence tomography (EDI SD-OCT; Heidelberg Engineering, Heidelberg, Germany).Results:
Ophthalmoscopic examination revealed a yellow choroidal mass measuring 6 × 6 mm with overlying subretinal fluid and involving the macular area in the right eye. In the left eye, there was a superior juxtapapillary yellow-colored mass involving the retina and measuring 1 × 1 mm. Optical coherence tomography revealed the subretinal fluid contouring a dome-shaped choroidal mass in the right eye and intraretinal nodular tumor superior to the optic disk of the left eye. Chest computed tomography revealed a pulmonary nodule measuring 2.5 mm × 1.4 mm, and biopsy of the liver metastasis confirmed the diagnosis of mucinous lung carcinoma.Conclusion:
The final diagnosis was presumed choroidal metastasis in the right eye and retinal metastasis in the left eye from underlying mucinous carcinoma of the lung.
