Histological examination reveals uniformly distributed round or oval polyhedral nevus cells containing giant melanosomes(macromelanosom). Although visual acuity is not disturbed in most cases, some visual deterioration or rarely malign transformation has also been reported. These patients should be examined once a year and the follow up examination should include fundus photography, and if indicated visual field examination and retinal nerve fiber thickness measurement. In this study, we discuss a 45 years old female patient presenting with the complaint of difficulty in near vision, whose biomicroscopic examination revaled a dark pigmented lesion on the right optic disc.trinfo:eu-repo/semantics/closedAccessAfferent pupillary defectMagnocellular nevusMelanocytesOptic disc melanocytomaArticle194285287Q4
