Identifying a metastatic choroidal tumor: a case study

Amelanotic lesions of the eye are more commonly seen in metastatic disease, whereas melanomas are usually melanotic and are not associated with pain. Metastatic tumors exhibit medium to high reflectivity pattern on ultrasound A scan, whereas melanomas usually display a low to medium pattern. A patchy, diffuse interocular mass with episcleral and/or orbital involvement is consistent with metastatic tumor of the eye, whereas melanomas tend to be more localized.
