Participants: Five patients with optic disc melanocytoma presented with visual complaints to a tertiary eye hospital in Saudi Arabia. Materials and Methods: Demographic and clinical data were analyzed, including the results of ocular examination, lesion laterality, best-corrected Snellen visual acuity, pupillary reflex, visual field testing, color fundus photography, fundus fluorescein angiography, and ophthalmic ultrasound. Results: Visual dysfunction secondary to optic disc melanocytoma was identified. Case 1 had macular star edema with mild tumor enlargement, Case 2 had optic atrophy, Case 3 had juxtapapillary choroidal neovascular membrane with macular involvement, Case 4 had optic disc swelling with an enlarged blind spot, and Case 5 had a large altitudinal visual field defect. Conclusion: Although melanocytomas of the optic disc tend to have a benign behavior with slow evolution and stable vision, they may adversely affect visual function through a variety of mechanisms. %K Melanocytoma %K Optic Disc %K Visual Function %U http://www.meajo.org/article.asp?issn=0974-9233;year=2010;volume=17;issue=3;spage=242;epage=245;aulast=Al-Rashaed
