| Optic
nerve head drusen are seen clinically as whitish-yellow irregularities on
the surface of the optic disc or deeper within the disc tissue causing an
irregularity to the disc, which may be mistaken for papilledema (#22084).
Histopathologically, drusen are seen as dark collections of
material in the optic nerve head anterior to the lamina cribosa. This material is acellular and stains darkly basophilic.
In addition, these lesions may also be calcified.
Drusen also stain positive for acid mucopolysaccharides.
