Ciliary body melanoma is a type of cancer arising from the coloured part (uvea) of the eye.
The tumour is usually diagnosed by clinical examination with a slit-lamp utilising a triple mirror contact lens.
Ultrasonography and fine-needle aspiration biopsy (FNAB) are also sometimes helpful in confirming the diagnosis.
Enucleation (surgical removal of the eye) is the treatment of choice for large ciliary body melanomas.
Small or medium sized tumors may be treated by an iridocyclectomy.
