A case report describing infrared autofluorescence findings in a case of optic disc melanocytoma (ODM): A 42 year old asymptomatic woman was diagnosed to have ODM in the left eye. Two years later, growth in the lesion was noted clinically. On infrared autofluorescence (IR-AF) imaging the lesion showed hypo-autofluorescence corresponding to the area of the pre-existing lesion surrounded by a more hyperautofluorescent arc temporally corresponding to the area of growth. We hypothesize that melanophagosome activity depleted the melanin content of the tumor which led to hypo IR-AF in a melanocytoma. Optical coherence tomography also contributed to the understanding of the infrared autofluorescence findings.
