Optic tract
|
Predominantly white matter structure found in diencephalon consisting of fibers originating in the retina. The optic tract is considered to extend from the point of the optic chiasm and terminates largely, although not exclusively, in the lateral geniculate complex. Other fibers end in the superior colliculus and other structures in the diencephalon, midbrain and brainstem (MM).

optic pathway glioma
|
Optic pathway glioma (OPG) is a benign tumor that develop along the optic nerve (chiasm, tracts, and radiations) characterized by impairment or loss of vision and may be accompanied by diencephalic symptoms such as reduced growth and alteration in sleeping patterns. OPG are often linked to neurofibromatosis type 1 (NF1, see this term).

Benign and malignant neoplasms which arise from or metastasize to the optic or second cranial nerve which extends from the optic disc of the eye and joins the optic chiasm. Clinical features may include visual loss, proptosis, and local pain. The majority of optic nerve tumors or optic gliomas.

Optic Nerve Glioma
|
Glial cell derived tumors arising from the optic nerve, usually presenting in childhood. Roughly 50% are associated with NEUROFIBROMATOSIS 1. Clinical manifestations include decreased visual acuity; EXOPHTHALMOS; NYSTAGMUS, PATHOLOGIC; STRABISMUS; pallor or swelling of the optic disc; and INTRACRANIAL HYPERTENSION. The tumor may extend into the optic chiasm and hypothalamus (MeSH).

Optic Pathways of CIVM postnatal rat brain atlas
|
The optic pathways are very easy to segment on coronal T2-weighted MRI. This pathway, comprised of optic nerves, optic chiasm, and optic tracts, is comprised largely of densely packed, myelinated axons, which appear quite dark on T2 MRI. The entire pathway can be segmented by simple seeded thresholding (magic wand) with a seed placed in the optic chiasm. The dorsal and caudal most extent of the optic tracts as the course lateral to the diencephalon can become quite thin, and may be difficult to distinguish depending on image resolution.
