Ciliary body melanoma appropriate in selected cases. Ciliary body melanoma Ciliary Body Melanoma is a type of cancer arising from the coloured part (uvea) of the eye. About 12% of uveal melanoma arise from the ciliary body. It occurs most commonly in the sixth decade. 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
Mammalian eye structures behind it: the vitreous humor, retina, choroid, and optic nerve. The radii of the anterior and posterior sections are 8 mm and 12 mm, respectively. The point of junction is called the limbus. On the other side of the lens is the second humour, the aqueous humour, which is bounded on all sides by the lens, the ciliary body, suspensory ligaments and by the retina. It lets light through without refraction, helps maintain the shape of the eye and suspends the delicate lens. In some animals, the retina contains a reflective layer (the tapetum lucidum) which increases the amount
