“…Spontaneous necrosis of optic disc melanocytomas 32,35 can occur and this may be complicated by secondary (neovascular) glaucoma. 36 Rarely, seeding of the vitreous with pigment particles has been described; in one case this was associated with migration of the particles into the anterior segment. [37][38][39] Although benign, optic disc melanocytomas may enlarge in size.…”

“…2 However, some have reported severe visual loss also. 10 Also in certain cases where melanocytomas enlarge rapidly and lead to sudden visual loss and necrosis can be found in the literature. 8,10,11 The major cause of decreased vision is attributed to the swelling of axons from compression of the nerve fibres and their vascular supply by the tumour.…”

Optic disc melanocytoma is a deeply pigmented variant of benign melanocytic nevus thathas been confused with malignant melanoma. Optic disc melanocytomas are locally invasivebut are not known to undergo transformation into malignant melanoma. We present anunusual case of a melanocytoma of the optic disc that is a coincidental fi nding on routinefundus examination even though the size of the melanocytoma is quiet large around 2.5 DD(3.7 mm) in size (while usually mean tumour diameter is 2 mm only) Follow up should remainthe primary approach in the management of the patients with optic nerve melanocytomasas they are benign, as previously advocated by Zimmerman.

“…A slow impairment of visual acuity attributed to the tumor is reported to occur in approximately 5% of cases. Cases accompanied by significant loss of visual acuity and/or visual field have also been reported 39–12. Similarly, in our cases, tumor-related visual impairment was due to macular exudation (Case 1), optic atrophy from optic nerve compression by the tumor (Case 2), and foveal choroidal neovascularization (Case 3).…”

Objective and Design:A retrospective review study was designed to describe five cases of optic disc melanocytomas with tumor-related visual impairment.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.
