A Comparison of Imaging Techniques for Diagnosing Drusen of the Optic Nerve Head

Drusen of the optic nerve head are diagnosed most reliably using B-scan echography compared with both preinjection control photography and CT scans. Preinjection control photography should be performed mainly when confirmation of visible drusen of the optic disc is desired. Neuroimaging using CT is suitable to exclude diagnosis of an intracranial mass lesion and possibly to detect buried drusen of the optic nerve head at the same time.
