What are the different types of intraocular melanoma?

Intraocular melanoma can be categorized based on the part of the eye that's affected. All intraocular melanoma forms in the middle layer of the eye, which is called the uveal tract. This includes the iris (the colored part of your eye), the ciliary body (a ring of muscle that adjusts the size of your pupil), and the choroid (the layer of blood vessels that surrounds your eye). Intraocular melanoma may affect any of those three parts. The most common type of intraocular melanoma is choroidal melanoma, which can be further broken down into small choroid melanoma and medium and large choroid melanoma, depending on the size of the growth. Metastatic intraocular melanoma can also occur, which can happen when intraocular melanoma spreads to other parts of the body such as the liver or lungs.
