Abstract
A 78-year-old man with a history of melanoma presented with a 2-week history of diplopia, pain, and intermittent blurriness in his right eye. Imaging showed a multicystic mass within the right lateral rectus muscle that was biopsy-proven metastatic melanoma. To our knowledge, this is the first case report of orbital metastasis from melanoma presenting as a multicystic mass intrinsic to the extraocular muscle with layering fluid-fluid levels.
