Nevus of Ota is a Rare Nevus and Q-switched Laser is the Best Available Option for Successful Treatment.

Patients with the nevus of Ota have increased amounts of melanin (pigment) and melanin-producing cells (melanocytes) in and around their eyes. This includes the intraocular blood vessel layer called the uvea (choroid, ciliary body and iris), on the sclera (the white part of the eye ball), and in the eyelids. Q-switched laser is the best available option for successful treatment.
