WebOptic Nerve Head Drusen: The Relationship Between Intraocular Pressure and Optic Nerve Structure and Function Lowering IOP in patients with ONHD has been proposed as a means to prevent progression of optic neuropathy. WebOptic disc drusen (ODD) are acellular deposits within the optic nerve head, well diagnosed by autofluorescence, echography, and enhanced depth-OCT. These deposits are often bilateral and lead to progressive visual field loss due to degenerative optic neuropathy [118] .
WebAdvances in spectral-domain optical coherence tomography (SD-OCT) of the optic nerve head (ONH) has proven to be a cost effective, noninvasive, outpatient procedure that may help. At its core are tools that quantify the thickness of the retinal nerve fiber layer (RNFL) and ganglion cell–inner plexiform layer (GC-IPL). WebOptic disc drusen (ODD) are present in 0.5%–3.7% of the population ( 1,2 ). Although the definitive etiology of ODD is not known, proposed risk factors include a small scleral canal, dysplasia of the optic nerve and its vasculature, and small optic disc size. Impairment of axonal transport in an optic nerve which may be congenitally abnormal ...
