Oculodermal melanocytosis or the Nevus of Ota means that there are increased numbers of cells called melanocytes in the eyelid skin, sclera and uveal vascular layer of the eye. Typically presenting at birth, it can increase during puberty and pregnancy. The pigmentation can follow the distribution of the trigeminal nerve and can therefore extend to the palate. The pigmentation and be complete or partial. When the eye is affected alone, it is called ocular melanosis. The increased numbers of melanocytes cause thickening of affected tissues and increase the patients risk for choroidal melanoma. Though there is no treatment for the pigmentation, close serial surveillance for malignant transformation and secondary glaucoma is warranted.
