Oman Journal of Ophthalmology, 2023 Optic nerve head (ONH) drusen are acellular calcified concretions. Buried drusen manifests as pseudopapilledema. The compressive effects of ONH drusen can rarely precipitate central retinal vein occlusion (CRVO).

Visual Field Defects in Patients With Optic Nerve Head Drusen [PDF]
Cureus, 2023 Background Optic nerve head drusen (ONHD) are acellular deposits in the optic nerve head, whose pathophysiology remains not fully understood. Most patients with ONHD have visual field (VF) defects. This study aims to describe the VF defects observed in patients with ONHD and to compare the anatomical and functional impairment between visible and buried

Optic Nerve Head Drusen in Black Patients [PDF]
Journal of Neuro-Ophthalmology, 2012 Several studies have suggested racial differences in the prevalence of optic nerve head drusen (ONHD). We aimed to determine the percentage of patients with ONHD who are black and to describe the clinical, ophthalmoscopic, and perimetric findings in these patients.We conducted a retrospective chart review of all patients with ONHD seen at our ...

Case report: bilateral optic nerve head drusen and glaucoma [PDF]
Romanian Journal of Ophthalmology, 2017 Optic nerve head drusen is an incidental finding in current ophthalmological practice. Although patients rarely display symptoms, structural, and functional defects, there are exceptional cases when clinical appearance can make it difficult to diagnose underlying or coexisting conditions, such as glaucoma.

Optic Nerve Head Drusen: An Update [PDF]
Neuro-Ophthalmology, 2018 Optic nerve head drusen are benign acellular calcium concretions that usually form early in life, just anterior to the lamina cribrosa. Improving imaging using optical coherence tomography suggests they are common and may be present in many clinically normal discs.

Optic Nerve Head Drusen Mimicking Optic Nerve Tumor [PDF]
Korean Journal of Ophthalmology, 2015 Dear Editor, Optic nerve head drusen (ONHD) are laminated hyaline bodies within the optic nerve head. Spectral-domain optical coherence tomography (SD-OCT) is a noninvasive optical imaging technique that provides high-resolution cross-sectional images of the retina, optic nerve head and retinal nerve fiber layer thickness. This technique thus offers

In-vivo high resolution imaging of optic nerve head drusen using spectral-domain Optical Coherence Tomography [PDF]
BMC Medical Imaging, 2010 Background Optic nerve head drusen (ONHD) are white calcareous deposits, seen either superficially on the optic nerve head or buried within it. Diagnosis of ONHD is made by one or more ways: clinical exam, autofluorescence, ultrasound of the optic nerve,

Optic Disc Edema and Optic Nerve Head Drusen
Journal of Neuro-Ophthalmology, 2013 We are concerned about the conclusions reported by Sarac et al (1) in their article entitled "Differentiation of optic disc edema from optic nerve head drusen with spectral-domain optical coherence tomography" and the application of these conclusions to clinical practice.
