Optic nerve head drusen.
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. Visual acuity is often not affected but the visual fields of these patients can be abnormal and deteriorate over ...
متن کاملBilateral Optic Disc Drusen Mimicking Papilledema
BACKGROUND Optic disc drusen, which are calcified deposits that form anterior to the lamina cribrosa in the optic nerve, may mimic papilledema. CASE REPORT We report herein three cases referred to us with suspicion of disc swelling and papilledema. Following ophthalmologic evaluation with B-scan ultrasound, red-free fundus photography, and computed tomography, the diagnosis of papilledema was...
متن کاملCT of drusen bodies and other calcific lesions of the optic nerve: case report and differential diagnosis.
One of the major causes of misdiagnosis of papilledema is buried drusen of the optic nerve head [1, 2]. Optic nerve drusen are calcified concretions of unknown etiology, located within the optic nerve head just anterior to the lamina cribrosa. As these concretions enlarge they may become visible ophthalmoscopically. When buried in the nerve head, they may cause difficulties in the ophthalmoscop...
متن کاملCLINICAL SCIENCES Differentiating Optic Disc Edema From Optic Nerve Head Drusen on Optical Coherence Tomography
Methods: Optical coherence tomographic images from 60 subjects (20 with ODE, 20 with ONHD, and 20 control subjects) were assessed qualitatively and quantitatively. Qualitative criteria for ODE included an elevated optic nerve head with smooth internal contour and subretinal hyporeflective space (SHYPS) with recumbent “lazy V” pattern. Optic nerve head drusen displayed a “lumpybumpy” internal op...
متن کاملDrusen of the optic disc. A retrospective study in cadaver eyes.
A retrospective study of 737 consecutive necropsies yielded 15 cases of drusen of the optic nerve head, an incidence of 20-4 cases per thousand. This represents the highest incidence yet reported. The histopathological features of drusen of the nerve head included elevation of the nerve head, compression of optic nerve fibres, partial optic atrophy, cytoid bodies, disc haemorrhages, juxtapapill...
