Glioblastoma of the optic chiasm

Journal of Clinical Neuroscience, 2007
Primary malignant gliomas of the optic nerve and chiasm are rare, and are usually rapidly fatal in adults. We report a 48-year-old woman with a glioblastoma multiforme arising from the optic chiasm. Following radiotherapy, our patient survived nearly 14 months, which is the longest survival reported in patients with this diagnosis. There have only been

Choristoma of the Optic Nerve and Chiasm

Archives of Ophthalmology, 1992
A 21-year-old patient with a biopsy-proved choristomatous malformation of the optic nerve and chiasm is presented. The patient experienced progressive unilateral vision loss and optic atrophy. A gadolinium-enhanced magnetic resonance image demonstrated chiasmal involvement that was not evident on computed tomographic scan or visual field testing.

Tumors of the optic nerve and optic chiasm

Journal of Neurosurgery, 1970
✓ In a series of 20 cases of glioma of the optic nerve, approximately 25% were successfully treated surgically. This series also confirms the observations of Taveras, et al., (1956) that 25% of patients thus treated obtain considerable additional improvement in vision after radiation therapy, and that another 10% derive minimal benefit.

The optic chiasm

Clinical Anatomy, 2011
The optic chiasm is formed when the optic nerves come together in order to allow for the crossing of fibers from the nasal retina to the optic tract on the other side. This enables vision from one side of both the eyes to be appreciated by the occipital cortex of the opposite side.

Traumatic Disruption of the Optic Chiasm

Journal of Neuro-Ophthalmology, 2009
A 27-year-old man developed a persistent bitemporal hemianopia after severe head trauma sustained in a high-speed motor vehicle accident. The initial brain MRI revealed hemorrhagic contusion of the optic chiasm. A brain MRI performed 4 weeks later demonstrated complete chiasmal transection, a phenomenon rarely documented with imaging.

Ganglioneuroma of Chiasm and Optic Nerves

Archives of Ophthalmology, 1961
Ganglioneuromas comprise an infrequent neural tumor characterized histologically by the presence of mature ganglion cells, nerve fibers, and neural supporting tissue. They are generally slow growing, nonmetastasizing, and are generally assumed to derive from sympathetic nerve tissue.

Tumors of the optic nerve and chiasm

Current Opinion in Ophthalmology, 1994
Optic nerve gliomas and meningiomas, which remain puzzling to clinicians, are reviewed with special attention to natural history, magnetic resonance findings, and appropriate management. New histopathological insights established the true neoplastic nature of optic nerve gliomas considered by most clinicians to be benign hamartomas.

Venous angioma of the optic chiasm

Annals of Neurology, 1978
AbstractA 30‐year‐old man presented with decreased vision in the right eye of three weeks' duration. Examination indicated a chiasmal syndrome and evidence of subarachnoid hemorrhage. CAT scan showed a large suprasellar mass. Surgical intervention confirmed the presence of a globular lesion filled with blood clots involving mainly the right side of the

Traumatic Dysfunction of the Optic Chiasm

Klinische Monatsblätter für Augenheilkunde, 2003
Trauma of the optic chiasm has been reported but its incidence is low.Retrospective review of patients diagnosed with traumatic optic neuropathy between 1992 and 2002.Among 91 patients with a diagnosis of traumatic optic neuropathy, 10 showed evidence of optic chiasm involvement. All were males, the average age was 32 years (range 22-43).
