Compression of the optic chiasm due to a lymphoreticular malignancy.

چکیده
A patient is described who presented with visual loss due to infiltration of the optic chiasm by chronic lymphocytic leukaemia. This case demonstrates intracranial infiltration as a primary presentation of chronic lymphocytic leukaemia without lymphoreticular involvement and, to our knowledge, is the first report of a chiasmal syndrome due to this lymphoproliferative disorder.

Electrophysiological and Histological Study of Lysolecithin-Induced Local Demyelination in Adult Mice Optic Chiasm
Introduction: Demyelination is one of the main causes of neurological disability. It is the end product of numerous pathological processes, multiple sclerosis (MS) being the most common cause. More than 70% of the MS patients suffer from optic disturbances. This disease commonly affects the optic pathway, particularly the optic nerves and chiasm. Several attempts have been made to produce a ...

Multiple sclerosis (MS) is one of the most autoimmune neurological and inflammatory disease in worldwide. Demyelination and disturbance of action potential conductance are regarded as main signs of MS disease. Hesperetin (Hst) is one of the flavonoid that have neuroprotective properties. The present study attempts to evaluate the effects of hesperetin or its nanoparticle on myelin repair and gl...
متن کاملNogo receptor blockade enhances subventricular zone’s stem cells proliferation and differentiation in demyelination context
Introduction: Nogo-A and Nogo receptor (NgR) are expressed in the subventricular zone (SVZ) stem cells. NgR plays critical inhibitory roles in axonal regeneration and remyelination. However, the role of NgR in SVZ niche behaviors in demyelination context is still uncertain. Here we investigated the effects of NgR inhibition on SVZ niche reaction in a local model of demyelination in adult mouse ...
متن کاملVisualization of Nerve Fiber Orientations in the Human Optic Chiasm Using Photomicrographic Image Analysis.
PURPOSE Hemidecussation of fibers entering the optic chiasm from the optic nerves is well recognized. The reason why bitemporal hemianopia results from chiasmal compression has not been fully explained. There is still a paucity of data relating to the precise details of the routes that the nerve fibers take through the chiasm and, in particular, where and how nerve fibers cross each other. This...

• Vol 7 • October 2005 Normal-Tension Glaucoma Open-angle glaucoma with normal intraocular pressure, also known as normal-tension glaucoma, is estimated to constitute 10–25% of all glaucoma cases. NTG is a diagnostic challenge, as various lesions affecting the visual pathways including compression by normal or abnormal intracranial blood vessels can mimic its clinical findings. In recent years,...
