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
Parasympathetic root of ciliary ganglion short ciliary nerves. These nerves enter the posterior aspect of the eyeball to innervate the sphincter pupillae and ciliaris muscles. The "sphincter pupillae" constricts the iris. The "ciliaris" muscle changes the shape of the lens, allowing the eye to focus on nearby objects (accommodation). Neither of these muscles is under voluntary control. Parasympathetic root of ciliary ganglion The parasympathetic root of ciliary ganglion provides parasympathetic innervation to the ciliary ganglion. The ciliary ganglion is a "parasympathetic" ganglion. Incoming parasympathetic nerve fibers form synapses with the dendrites of nerve cells within the ganglion. However, the ciliary ganglion is not simply a
