Ocular melanosis is a condition where there is a significant amount of melanin pigmentation in the eye, particularly in the iris and conjunctiva. Other words used to refer to this condition include ocular melanocytosis, ocular melanodermatitis, and iris melanosis. Melanosis oculi, ocular melanocytic hyperplasia, and conjunctival melanosis are other synonyms. The condition is typically benign, though in rare instances it can be associated with the development of ocular tumors. The treatment for ocular melanosis is usually monitoring and observation, with any potential changes in the pigmentation being carefully monitored by an experienced eye doctor or ophthalmologist.
