When it comes to choroidal melanoma, many people may not know that it is actually a common intraocular tumor that seriously endangers the patient's eye health. So what exactly is choroidal melanoma? Let's briefly talk about choroidal melanoma.

Choroidal melanoma is a tumor composed of malignant melanoma cells that arise from melanocytes within the choroidal stroma.

The incidence of choroidal melanoma in China ranks second among intraocular tumors, second only to retinoblastoma in children. Site of onset: Choroid is the most common, accounting for 78% to 85%; followed by ciliary body, accounting for 9% to 12%; iris accounts for 6% to 9.5%. Eye: The left and right eyes are similar. Most cases occur in one eye, and bilateral cases are rare. Race: The ratio of the incidence rate of colored people to white people is 1:165 to 1:250. Geographical environment: North America has the highest incidence, followed by Europe, Asia and Latin America are less common, and Africa is rare. Age of onset and gender: The minimum reported age of onset is 7 and a half months, the maximum is 70 years old, the average is 40 to 50 years old, and 51 to 60 years old is the most common age.
