The paper presents young female patient with bilateral optic nerve drusen and standard automated perimetry, B-scan ultrasonography, CT, OCT, HRT, GDx, 


Line scan images with a 4.0-mm diameter (radius, 2.0 mm) that were obtained from the fast optic disc scans on optical coherence tomography. The images represent a normal optic nerve (A), optic nerve head drusen with moderate (B) and marked (C) elevation, and optic disc edema with mild (D), moderate

The current methods of diagnosing optic nerve head drusen include direct visualization with ophthalmoscopy, fundus photography (Figure 1A), autofluorescence with fluorescein angiography (Figure 1B), computerized tomography, and B-scan ultrasonography (Figure 1C). The patient has optic disc protrusion caused by optic disc drusen. B. The PHOMS (red overlay) surrounds a large portion of the optic disc causing blurred margins. C. Optic nerve head scan in a patient without blurred disc margins. No PHOMS is visible and there is no disc protrusion. Asterisks indicate ODD. Red arrows indicate blood vessels.

Drusen of the Optic Nerve. Drusen can also occur in the optic nerve. These drusen are made up of protein and calcium salts and generally appear in both eyes. Unlike the drusen associated with AMD, optic nerve drusen (also known as optic disc drusen) are not related to aging, may be inherited, and typically appear in children.

Noël LP, Clarke WN, MacInnis BJ. Distinguishing between anomalous elevation of the optic disc caused by buried drusen and true papilledema can often be clinically difficult. Funduscopy showed bilateral optic disc edema. Findings on brain imaging were normal, and a diagnosis of idiopathic intracranial hypertension was confirmed after lumbar puncture showed an elevated opening pressure of 32 cm H(2)O.

The earliest signs of drusen formation histologically are small globular or plaque-like deposits in Bruch membrane of hyaline material, present in the majority of individuals, and perhaps congenital in nature 3 .

B-scan ultrasonography is recognized as the most sensitive and reliable method for diagnosing optic nerve head drusen. 1 Fine-slice computed tomography through the optic nerves is also an

Since children as well as adults are affected, it is important to consider optic nerve head drusen in the differential diagnosis of papilledema or optic nerve swelling. Definition Standardized A-scan echography also helped to confirm the diagnosis of pseudotumor cerebri (2 patients) and optic neuritis (2 patients), emphasizing the need for performing a thorough evaluation before attributing clinical findings of an ophthalmoscopically abnormal optic nerve head to optic disc drusen. The B‐scan provides a bidimensional anatomic image of the optic nerve head, and the A‐scan enables the cross‐sectional measurement of the ONW. Detection of the ‘doughnut’ or ‘crescent’ sign in the B‐Mode, an ONW of >3.3 mm in the retrobulbar area as observed in the A‐Mode, or a positive 30‐degree test was considered positive US findings. When the clinician was not certain of the patient's race, the patient was asked to report their race. We included only black patients who had ONHD confirmed on either fundus examination or B-scan ultrasonography.
