Bedside Optic Nerve Ultrasonography for Diagnosing Increased Intracranial Pressure
Annals of Internal Medicine, 2019Background Optic nerve ultrasonography (optic nerve sheath diameter sonography) has been proposed as a noninvasive, quick method for diagnosing increased intracranial pressure.

UMSC-derived exosomes promote retinal ganglion cells survival in a rat model of optic nerve crush.
Journal of Chemical Neuroanatomy, 2019Traumatic optic neuropathy or glaucoma lead to retinal ganglion cells loss and cause blindness, and there is no effective therapy strategy by far. Mesenchymal cells from the Wharton's jelly of the umbilical cord (umbilical cord mesenchymal stem cells ...

As a comprehensive ophthalmologist, I have no familiarity with the primary literature concerning ophthalmic anatomy and histology. Thus, I am in no position to declare which book is correct regarding points on which they differ.

Optic nerve glioma mimicking an optic nerve meningioma
Clinical Neurology and Neurosurgery, 1996The case is described of an optic nerve glioma, mimicking an optic nerve meningioma in a man aged 41 years. CT, MRI and DSA revealed an enhancing tumor surrounding the optic nerve. Histopathologic examination of the removed optic nerve revealed a centrally located glioma surrounded by normal optic nerve fibres.

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.

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 ...

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 ...

Annals of Diagnostic Pathology, 2005
Choristomas are rare lesions that typically involve peripheral nerves and are marked by the presence of histologically normal tissue for an organ or body part other than the site at which it is located. Reports of choristoma involving cranial nerves are extraordinarily rare.

Two case reports, one clinical and the other pathologic, illustrate important features of optic nerve drusen. A clinical subject demonstrates that optic nerve drusen cause visual field defects and central visual loss in childhood. Another case, studied postmortem, illustrates optic atrophy caused by drusen.

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 ...
