Improvement of diencephalic syndrome after partial surgery of optic chiasm glioma.

30 Aug 2009 A 10-month-old male presented with sudden growth failure and cachexia. MRI showed a chiasma of the hypothalamic mass. Biopsy was avoided due to operative risks. Three cycles of chemotherapy were given, resulting in stable disease on MRI, but growth ... Read more...

Bilateral visual field maps in a patient with only one hemisphere.

18 Jul 2009 In mammals smooth retinotopic maps of the visual field are formed along the visual processing pathway whereby the left visual field is represented in the right hemisphere and vice versa. The reorganization of retinotopic maps in the lateral ... Read more...

In vivo diffusion tensor imaging of the human optic chiasm at sub-millimeter resolution.

7 Jun 2009 In this work we report findings from an in vivo diffusion tensor imaging (DTI) study of the human optic chiasm at sub-millimeter voxel resolution. Data were collected at 3 T using a diffusion-weighted radial-FSE sequence, which provides images free ... Read more...

Technical information about 'Optic Chiasm'

Definition: The X-shaped structure formed by the meeting of the two optic nerves. At the optic chiasm the fibers from the medial part of each retina cross to project to the other side of the brain while the lateral retinal fibers continue on the same side. As a result each half of the brain receives information about the contralateral visual field from both eyes.
