The optic nerve

Current Opinion in Neurology, 1996
Recent articles in the scientific literature have described major advances in our understanding of the anatomy and vascular relationships of the optic nerve (cranial nerve II) and of the diagnosis and treatment of a variety of disorders affecting this nerve, including congenital anomalies of the optic disc, dominant hereditary optic neuropathy ...

Imaging of the optic nerve

European Journal of Radiology, 2010
This article provides an overview of the imaging findings of diseases affecting the optic nerve with special emphasis on clinical-radiological correlation and on the latest technical developments in MR imaging and CT. The review deals with congenital malformations, tumors, toxic/nutritional and degenerative entities, inflammatory and infectious ...

Hypoplasia of the Optic Nerve

Archives of Ophthalmology, 1978
Premorbid ophthalmoscopic and histopathologic findings were correlated in a case of bilateral optic nerve hypoplasia in a 9-month-old infant with bilateral hydranencephaly. The double-ring sign was due to an extension of retina and retinal pigment epithelium (RPE) over the outer portion of the lamina cribrosa.

Optic nerve glioma

Clinical Radiology, 1980
A series of 10 patients with optic nerve glioma involving the chiasm is presented, all treated by radiotherapy. In a follow-up period varying from six months to 17 years, none has died of the tumour and four have shown improvement of vision. In an attempt to determine whether or not treatment with radiotherapy is beneficial the results of six other ...

Evulsion of the optic nerve

Documenta Ophthalmologica, 1989
Optic nerve evulsion is an uncommon traumatic event, which may result from various orbital or facial injuries. Two patients in whom clear media permitted prompt diagnosis are described. The possible mechanisms are not quite clear, but extreme rotation of the globe seems to play an important role.

Optic Nerve Aplasia

Archives of Ophthalmology, 1992
Optic nerve aplasia is a rare congenital defect invariably associated with other ocular or systemic disorders. We examined a 3-year-old girl with monocular microphthalmos who had optic nerve aplasia on histopathologic examination of the eye after enucleation.

Save the Optic Nerve

Archives of Ophthalmology, 1993
To the Editor. —Aiello et al, 1 in their correspondence in the September 1992 issue of theArchives, reported two cases of spontaneous improvement of progressive anterior ischemic optic neuropathy (AION). While I do not doubt their results, it must be noted that significant visual field defects remain. The poor prognosis in cases of AION, including the

Optic Nerve: The Glaucomatous Optic Nerve

2009
Glaucoma is an optic neuropathy. Although there are several pathophysiologies that must be managed in the clinical care of the glaucoma patient, what defines all forms of glaucoma is an optic neuropathy that demonstrates classic and recognizably variable [1–6] structural and functional behaviors.

Optic Nerve Hypoplasia

Journal of Pediatric Ophthalmology & Strabismus, 1978
Optic nerve hypoplasia is rarely met in otherwise normal eyes. Three unilateral cases of patients with small optic disks, reduced visual acuity, and convergent squint on the affected eye are presented. The anomaly is probably caused by failure of development of the ganglion cell layer of the retina causing a small optic nerve head with normal central ...

Orbit and Optic Nerve

Topics in Magnetic Resonance Imaging, 1996
The optic nerve is a fiber tract of the brain, and is not a true cranial nerve. Primary pathologic processes seen in the central nervous system and its linings can therefore affect the optic nerve. Along their course the fibers of the visual pathways are also susceptible to secondary extrinsic processes.
