Purpose. Intraocular metastasis from gastric cancer is not common and metastatic carcinoma to the vitreous or retina is exceedingly rare. We describe a case of gastric cancer metastatic to the vitreous and retina. Methods. Retrospective, single-center case report. Results. A 64-year-old woman with advanced gastric cancer with multiorgan metastatic disease presented with decreased visual acuity. Ophthalmoscopy revealed extensive overlying vitreous seeds and macular infiltrations in both eyes. Fine-needle aspiration cytology from the vitreous confirmed the diagnosis of metastatic carcinoma. Conclusions. We report an extremely rare case of vitreous and retinal metastasis from gastric cancer. Ophthalmologists and oncologists should be aware that gastrointestinal cancer can cause intraocular metastasis in the form of vitreous seeds and retinal infiltration.
