WebOptic nerve head drusen (ONHD) are acellular deposits of calcium, amino and nucleic acids, and mucopolysaccharides, buried or at the surface of the optic disc ( 1–3 ). When located near the surface, drusen can be directly visualized by ophthalmoscopy. Superficial drusen typically confer an irregular lumpy appearance to the optic disc ( 4 ).
