The 'nevus of Ota' is a usually congenital (meaning you are born with it) condition in which darkly pigmented cells collect in the skin and tissue of the face around the eye (and sometimes in the eye) giving the area a bluish or grayish discoloration. Usually, the condition is not medically serious, meaning that it principally should be treated for cosmetic reasons, as large areas of facial pigmentation can cause significant social distress later in life. Rarely, the nevus of Ota can give rise to melanoma, which is a very serious form of skin cancer, and it can also be associated with glaucoma, or rise in the pressure within the eye.
Laser based therapy is the standard of care for treating nevus of Ota. Usually multiple sessions (4-8) are required, but the results are excellent with virtually all patients showing either complete resolution or very significant improvement in the discoloration. The risks from the laser procedure are very minimal and it is tolerated very well.
