Choroidal metastatic tumours from gastric cancer (GC) are rare compared with breast and lung cancer. Here, we report a patient with GC who presented to our ophthalmology clinic with a one-week history of left eye visual disorder and pain. Fundoscopic and B-scan examinations suggested a choroidal metastatic tumour. Computed tomography (CT) and magnetic resonance imaging (MRI) scans confirmed our initial diagnosis. Histopathology and immunohistochemical findings showed the tumour most likely originated from the gastrointestinal tract. Although the patient was well after eye removal, he died two months after surgery. Metastasis of GC should be a consideration when a patient with a history of GC presents with eye pain, decreased vision, and/or high intraocular pressure.
