Naevus of Ota

Learn more about Naevus of Ota,
this rare and unique condition
that affects the skin and eyes.  

Naevus of Ota, also known as oculodermal melanocytosis, is a non-hereditary hyperpigmentation disorder that causes brown, blue, or gray patches on the skin. It's most often found on the inside of the eye, but can also appear on the forehead, nose, cheek, periorbital region, and temple.

Naevi of Ota & Ito are melanocytic skin growths for which no effective therapy was available until laser therapy was developed. Laser therapy is being successfully used for the removal of these naevi.


At the VIP Laser Clinic Med Spa, Q-Switched Nd: YAG laser has shown the best results in eliminating the Naevus of Ota.


Patients need an average of three to five sessions of laser treatment for the complete removal of the Naevus of Ota. There are no complications and side effects.

Naevus of Ota

The Naevus of Ota, which originally was described by Dr M.T. Ota and Tanino (Japan) in 1939, is a hamartoma of dermal melanocytes. which clinically presents itself as a blue, grey or dark grey patch on the face, and is congenital or acquired and is within the distribution of the ophthalmic and maxillary branches of the trigeminal nerve. The naevus of Ota can be unilateral or bilateral, and, in addition to skin, it may involve ocular and oral mucosal surfaces.The sclera is involved in two-thirds of cases, causing an increased risk of glaucoma. It should not be confused with Mongolian spot, which is a birthmark caused by entrapment of melanocytes in the dermis but is located in the lumbosacral region. Women are nearly five times more likely to be affected than men, and it is rare among white people. Naevus of Ota may be congenital or not, and may appear during puberty.
