The 20 Best Uveal Melanoma Doctors in North Korea

Intraocular melanoma is a cancer of the pigment-producing cells (melanocytes) in the middle layer of the eye, called the uveal tract. The uveal tract has 3 main parts: (1) the choroid (the tissue layer filled with blood vessels); (2) the ciliary body (the ring of muscle tissue that changes the size of the pupil and the shape of the lens); and (3) the iris (the colored part of the eye). Most cases of Intraocular melanoma develop in the choroid, called choroidal melanoma. The ciliary body is less commonly a site of origin, and the iris is the least common. Each manifests with different clinical features and symptoms.
