Archives of Ophthalmology, 1984
To the Editor. —In their article in the MayArchives, Bec et al 1 reported on the identification of optic nerve drusen with computed tomography (CT). This capability is well known. Using this method to detect drusen is not cost-effective (a CT scan costs $300 to $400) and exposes the patient to unnecessary radiation.

Seminars in Ophthalmology, 2003
Optic disc drusen are congenital and developmental anomalies of the optic nerve head seen commonly in clinical practice, often as an incidental ophthalmologic finding during routine exams. Optic disc drusen are a form of calcific degeneration in some of the axons of the optic nerve.

Optic Nerve Head Drusen and Glaucoma
Archives of Ophthalmology, 1985The simultaneous occurrence of both optic nerve head drusen and glaucoma may make it difficult to evaluate visual field defects and the appearance of the optic nerve head. We saw five patients with both conditions, of whom four had pigmentary glaucoma or pigmentary dispersion syndrome. Drusen do not preclude the development of cupping, and they make it

In Reply. —We agree with Dr Beck that the diagnosis of optic nerve head drusen is most often easy with ophthalmoscopy. However, in some instances, the diagnosis may be difficult, even with the help of fluorescein angiography. In these cases, CT is helpful by showing typical calcifications and eliminating a cerebral tumor or optic nerve compression ...

Optic Nerve Head Drusen and Pseudotumor Cerebri
Archives of Neurology, 1988A 42-year-old woman presented with a history of headache. Results of funduscopic examination revealed elevated disc margins and bilateral optic nerve head drusen. Lumbar puncture, head computed tomography, and fluorescein fundus angiography results were consistent with the diagnosis of pseudotumor cerebri and coexistent disc drusen.

Scleral Canal Size and Optic Nerve Head Drusen
American Journal of Ophthalmology, 1985From projected optic disk photographs we measured the size of the scleral canal in two samples of emmetropic patients: one of patients with unilateral pseudopapilledema and drusen and the other of the general normal population. Measurements on the non-drusen-containing optic disk of patients with unilateral drusen were taken to reflect the scleral ...

Drusen in the Optic Nerve Head
Archives of Ophthalmology, 1978Five patients with a clinical diagnosis of buried or exposed drusen of the optic nerve head were examined by computerized tomography (CT). The relative x-ray absorption within their nerve heads was significantly larger than in controls, reflecting the high calcium content of drusen.

Legal Blindness From Severe Optic Nerve Head Drusen
JAMA Ophthalmology, 2016A man in his late 40s presented for evaluation of progressive visual acuity and visual field loss in both eyes over a 10-year period. Best-corrected visual acuity was 20/200 OD and counting fingers OS. No afferent pupillary defect was present. Goldmann perimetry revealed severe field constriction in each eye.
