Clinical and morpho-functional results of a second examination of a patient with optic nerve head drusen taken after a long-time interval (27 years)

Abstract

Optic disc drusen (ODD) is a bilateral anomaly of the optic nerve, in which hyaline calcified intercellular inclusions appear in the optic disc head area in front of the cribriform plate. As a rule, in the early stages, ODD patients have no complaints, central vision does not suffer, while perimetry data may show an expansion of the blind spot and narrowed visual field. As complications are developing and the optic nerve atrophy is progressing, visual acuity may decrease. The visual functions are deteriorating gradually. In the clinical case discussed, a patient with optic disc drusen was examined for a second time after a prolonged interval (27 years).The ophthalmoscopic picture and functional parameters obtained during this examination clearly confirmed the unfavorable course of optic disc drusen and the need for such patents to be regularly examined for changes in visual functions (visual field), the state of the retina and the optic nerve.
