Purpose:
To report a treatment approach for advanced extrascleral uveal melanoma.
Methods:
We performed clinical examination including magnetic resonance imaging, computed tomography, angiography, and histopathologic analysis.
Case:
A 49-year-old healthy woman presented with a 7-year history of an enlarging pigmented mass in her right orbit. Malignant melanoma was diagnosed after biopsy with immunohistochemical stains. Treatment included selective intra-arterial embolization.
Results:
A significant reduction in tumor burden was seen 3 months after intra-arterial embolization. No complications were associated with the treatment.
Conclusion:
Selective intra-arterial embolization may allow adequate palliative therapy in select cases of advanced extrascleral uveal melanoma.

Overview of Advanced Functional Groups
Functional groups are groups of atoms with specific chemical properties that occur within organic molecules and are sometimes denoted as “R”. Functional groups can “functionalize” a compound by enabling it to adopt different physical and chemical properties.
