/ Treatment / What is intraocular melanoma? Intraocular melanoma, a rare cancer, is a disease in which cancer (malignant) cells are found in the part of the eye called the uvea. The uvea includes the iris (the colored part of the eye), the ciliary body (a muscle in the eye), and the choroid (a layer of tissue in the back of the eye). The iris opens and closes to change the amount of light entering the eye. The ciliary body changes the shape of the lens inside the eye so it can focus. The choroid layer is next to the retina, the part of the eye that makes a picture. The uvea contains cells called melanocytes, which contain color. When these cells become cancerous, the cancer is called a melanoma. Intraocular melanoma occurs most often in people who are middle aged. If there is melanoma that starts in the iris, it may look like a dark spot on the iris. If melanoma is in the ciliary body or the choroid, a person may have blurry vision or may have no symptoms, and the cancer may grow before it is noticed. Intraocular melanoma is usually found during a routine eye examination, when a doctor looks inside the eye with special lights and instruments. The chance of recovery (prognosis) depends on the size and cell type of the cancer, where the cancer is in the eye, and whether the cancer has spread. / Treatment / |
