Abstract

Introduction: Nevus of Ota or Oculodermal Melanocytosis is hyperpigmentation of facial skin in the distribution of the first & second divisions of trigeminal nerve. They are frequently associated with ipsilateral melanocytosis of the conjunctiva, sclera, cornea & uveal tract. Approximately 10% of cases are bilateral. We report a case of 80 year old female patient presenting with bilateral pigmented areas over all the three divisions of trigeminal nerve on both sides and also extending to hard palate, soft palate, buccal mucosa and nasopharyngeal mucosa. This patient also has bilateral open angle glaucoma.
Conclusions: Bilateral involvement is rare with nevus of Ota; involvement of such extensive nature along with bilateral open angle glaucoma has never been reported in the literature to the best of our knowledge.
