Optical coherence tomography/scanning laser ophthalmoscopy (OCT/SLO) of normal control and optic nerve head drusen. (Top) Transverse OCT/SLO scan of healthy optic nerve, demonstrating smooth Background Optic nerve head drusen (ONHD) are white calcareous deposits, seen either superficially on the optic nerve head or buried within it. Diagnosis of ONHD is made by one or more ways: clinical exam, autofluorescence, ultrasound of the optic nerve, CT scan and/or visual field examination. The present study describes features of ONHD based on another diagnostic modality, the spectral Optic disc drusen, which are calcified deposits that form anterior to the lamina cribrosa in the optic nerve, may mimic papilledema. We report herein three cases referred to us with suspicion of Acute swelling of the optic nerve; Splinter hemorrhage; Ischemic optic neuropathy Fluoresecein angiography: Undilated capillary network with no leakage of dye into the peripapillary region. Discrete foci of hyperfluorescence with late staining of the drusen. B-scan ultrasound is helpful in detecting buried drusen.
1). A-scan measured the diameter of the optic nerves … lude B-scan ultrasonography, fundus autofluorescence, and optical coherence tomography (OCT). These modalities are useful for drusen detection but are limited by low resolution or poor penetration of deep structures. This review was designed to assess the potential role of new OCT technologies in imaging ONHD.

These drusen are made up of protein and calcium salts and generally appear in both eyes. Unlike the drusen associated with AMD, optic nerve drusen (also known as optic disc drusen) are not related to aging, may be inherited, and typically appear in children.
