What should you know about orbital melanoma?

Melanoma can arise in skin near the eyelids or in tissues within the orbit, and the exact site affects the assessment. A changing dark spot, a new lump, persistent swelling, bleeding, pain, drooping, double vision, or a change in the position or movement of the eye needs examination. These symptoms do not by themselves prove melanoma; many eye and skin problems have other explanations. Diagnosis may involve an examination, imaging, and a biopsy when a specialist considers it appropriate.

Arrange prompt review with an appropriate eye, skin, or cancer specialist if melanoma is suspected. The team may discuss Surgical Excision or Skin Cancer Surgery when the tumour can be removed, while Tumour Removal Surgery describes broader surgical planning. Additional evaluation can show whether nearby lymph nodes or other areas need attention; a Sentinel Lymph Node Biopsy may be considered in selected cases. Treatment can also involve Immunotherapy, depending on the tumour's site, extent, and pathology.

Seek urgent medical care for sudden vision loss, severe eye pain, rapidly increasing swelling, a rapidly changing or bleeding lesion, new weakness, confusion, severe headache, or repeated vomiting. These symptoms may have several causes, but they should not wait for a routine appointment. After treatment, attend planned reviews because Follow-Up After Cancer Treatment helps the team check the treated area and assess for new concerns.

Ask where the melanoma began, whether a biopsy is needed, what the imaging shows, which treatment preserves useful eye function, whether lymph-node assessment is appropriate, and how follow-up will be organised.
