A 21-year-old man with blind left eye due to trauma sustained 3 years before complained of severe pain in the left eye, headache and vomit for eight days. The only systemic compromise referred by the patient was weight loss of 10 kg. Clinical examination revealed total retinal detachment with subretinal pigmented lesion. Ultrasonographic examination disclosed a dome shaped tumor with homogeneous structure, low reflectivity and signs ofvascularity, suggesting choroidal melanoma. Enucleation was performed and histopathologic examination showed spindle cell choroidal melanoma. We encourage routine ultrasonography examination of blind eyes.
