Nevus of Ota is a a melanocytic proliferation that occurs around the eye which I occasionally encounter in both my The Woodlands dermatology and Conroe dermatology offices.  The skin innervated by the first and second branch of the trigeminal nerve is typically involved.  The affected area will have a bluish grey color and the sclera (white of the eye) and oral mucosa may also be involved. Most patients with Nevus of Ota are women and it is present at birth and remains throughout life.  In most cases, a Nevus of Ota is benign but malignant degeneration can occur with the most common site being the choroid of the eye.  Ophthalmologic evaluation is recommended for patients with Nevus of Ota as glaucoma can occur.  Treatment is not necessary but if cosmetically desired a Q switched laser can be used.
