Abstract

PURPOSE:To investigate if a congenital anomaly of the head of the optic nerve like such as tilted disc can be a risk factor for the development of optic disc drusen.METHODS:The study was performed retrospectively on the files of 47 patients with optic disc drusen. The diagnosis was confirmed by fluorescein angiography and B-scan ultrasonography. The authors examined the fundus photographs and the fluorescein angiographies of these patients looking for the presence of tilted discs.RESULTS:Two of the 47 patients with optic nerve drusen had tilted discs as well, about twice the expected rate. Both cases presented a parapapillary hemorrhage.CONCLUSIONS:The concomitant presence of tilted disc and optic disc drusen can have a cause-effect relationship. The axonal crowding in a scleral canal of reduced size, as seen in tilted disc, can compress the nerve fibers against the stiff lamina cribrosa, producing a chronic optic neuropathy leading to drusen.
