An optic pathway glioma is a subset of low grade astrocytoma that grows in a portion of the optic pathway (optic nerve, optic chiasm, optic radiations). Optic gliomas typically grow as an infiltrative lesion with poorly defined borders.
Mammalian optic nerve regeneration following the application of electric fields. Risk factors for gliomas and meningiomas in males in Los Angeles County.
People with neurofibromatosis are more likely to develop them. Advanced optic nerve glioma can cause vision loss. An individual who suffers from an optic nerve glioma is likely to experience some degree of vision impairment. Peripheral vision loss is most common, but an advanced glioma can affect all aspects of sight.
It represents 5% of brain tumors in children. The diagnosis is always made on the occasion of ophthalmological clinical signs (nystagmus, loss of visual acuity). Optic nerve glioma is the most common optic nerve tumour. However, it has an unpredictable natural history.

Another name for this tumour is a pilocytic astrocytoma. Patients who get this tumour commonly have an under lying medical condition called neurofibromatosis type 1. Optic glioma Gliomas are tumors that grow in various parts of the brain. Optic gliomas can affect: One or both of the optic nerves that carry visual information to the brain from each eye 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.

(See "Classification and pathologic diagnosis of gliomas".) The classification, diagnosis, natural history, and management of OPGs will be reviewed here. On histology, optic pathway gliomas are characterized by moderately and variably cellular tumor nuclear cell density, in a fibrillary background (see Figure 4 for typical histology). The tumors are invariably GFAP-positive and Rosenthal fiber/eosinophilic granular bodies are common. Thickened/hyalinized small vessels may be seen. Optic nerve glioma Optic nerve gliomas represent 65% of all intrinsic optic nerve tumors. Approximately one-third of all optic pathway gliomas occur in the setting of neurofibromatosis type 1. The clinical presentation is determined by the size, location, and extent of the tumor, but 90% of the lesions are symptomatic by the second decade.

Optic glioma · One or both of the optic nerves that carry visual information to the brain from each eye · The optic chiasm, the area where the optic nerves cross each An optic pathway glioma occurs along the nerves that send messages from the eye to the brain (the optic pathway) and can occur anywhere along its path. 25 Feb 2021 Optic pathway gliomas are benign CNS tumors that primarily affect children. Although typically slow growing, the location of these tumors makes Eighty-five cases of histologically verified gliomas of the optic nerve or chiasm were studied retrospectively.
