Drusen of the Optic Disc

open access: yesCurrent Neurology and Neuroscience Reports, 2008
Optic disc drusen are acellular calcific deposits occurring in small, crowded optic discs with abnormal vasculature. Evidence suggests axoplasmic transport alteration and axonal degeneration are involved in disc drusen formation. In affected patients, the number and size of disc drusen are highly variable, and the drusen may be visible near the disc ...

Optic Disc Drusen in Tilted Disc

open access: yesEuropean Journal of Ophthalmology, 2005
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 ...

Drusen of the Optic Disc

Survey of Ophthalmology, 1977
Although optic disc drusen have been of interest to ophthalmologists for more than 100 years, their etiology and many aspects of their relationship to other clinical conditions remain obscure. They have been clinically observed in 0.3% of the population, although autopsy studies suggest an incidence of 2%.

[Optic disc drusen].

open access: yesDer Ophthalmologe : Zeitschrift der Deutschen Ophthalmologischen Gesellschaft, 2008
Optic disc drusen (ODD) are an initially symptom-free, usually bilateral, progressive type of optic neuropathy with genetic disposition. We observed visual field loss (VFL) in 64% (49 of 77) of our patients. Vascular complications such as AION are common.

Optic Disc Drusen: Complications and Management

Optometry - Journal of the American Optometric Association, 2007
Disc drusen have been found clinically in 0.3% of the population with up to 91% presenting bilaterally. Disc drusen gradually change in their ophthalmoscopic appearance throughout a patient's lifespan. This case highlights the possible ocular complications of disc drusen and the complexity in their treatment because of the risk of visual acuity loss.A ...
