SPOTS, TYPES AND CAUSES These spots unlike moles are more of a lesion or nevus, mostly flat or may be slightly raised in either black, pink or brown color.

Also known as pigmented tumors, these spots or freckles are almost harmless. The most common of the eye tumors is Congenital nevi besides others like conjunctival melanoma and melanosis. Nevi is caused due pigmentation cells or over growth of melanocytes. Most of the people who have nevi have it since their birth or it surfaces in their early childhood itself. Usually the spot might not be noticeable until puberty because at this age it becomes bigger and darker too.
While primary acquired melanosis usually occurs in the middle to people with fair skin and suddenly too.
The most - rare form is the Conjunctival melanosis and either occurs suddenly or as primary acquired melanosis.
TREATMENT As per the eye cancer network most eye pigmented lesions are benign in nature and practically harmless. But, the eye specialists need to monitor these lesions to check for any signs of shape change and growth. Particular attention needs to be paid on whether the lesion extends to the cornea or develops and increase in blood supply. As compared to malignant lesions the benign nevi grows at a slower rate. In case there is any change in shape or size of the lesion the doctor might advise a biopsy but congenital nevi becoming cancerous is extremely rare even if it shows change in shape or size.
