+A 28-year-old woman was referred for multimodal imaging (Nidek, Mirante) of asymptomatic optic nerve head drusen.
+A - Retromode imaging was performed and demonstrated the limits and number of optic nerve head drusen, which seem to be organized in a grape-like network of different sizes and densities.
+B - Color fundus photography showed fuzzy papillary margins (pseudoedema).
+C - Autofluorescence photography showed diffuse hyper-autofluorescence of the drusen.
+D - Performing OCT B-scan was useful to present the different densities of the drusen, which appear as circular structures.
