—It is clear that optic disc drusen may be observed in anomalously elevated optic discs. It has also been assumed that anomalously elevated optic discs without visible drusen nevertheless contain drusen that are "buried" below the surface of the disc, which become visible with time.1,2 If this were true, one would expect patients with anomalously elevated optic discs without visible drusen to be generally younger than patients with visible drusen. This does not appear to be the case.3Mullie and Sanders4 have used computed tomographic scanning to identify buried drusen in four optic discs of three patients with no ophthalmoscopic or fluorescein angiographic evidence of drusen; however, to my knowledge, there has never been photographic documentation of the appearance of optic disc drusen in a patient whose optic discs initially were simply anomalously elevated. I have recently seen such a patient.
