Ciliary body melanoma 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.

Choroid plexus Choroid plexus The choroid plexus is a plexus of cells that produces the cerebrospinal fluid in the ventricles of the brain. The choroid plexus consists of modified ependymal cells. There are four choroid plexuses in the brain, one in each of the ventricles. Choroid plexus is present in all parts of the ventricular system except for the cerebral aqueduct, the frontal horn and the occipital horn of the lateral ventricles. The choroid plexus consists of a layer of cuboidal epithelial cells surrounding a core of capillaries and loose connective tissue. The epithelium of the choroid plexus is continuous with the
