WebDec 2, 2024 · Optic pathway gliomas (OPGs; also referred to as optic gliomas) are low-grade astrocytic tumors that occur in the optic nerve, chiasm, or both. They occur sporadically and in patients with neurofibromatosis type 1 (NF1). Although often indolent, OPGs can cause clinical symptoms due to mass effect and visual loss. WebThe visual pathway describes the anatomical pathway by which electrical signals generated by the retina are sent to the brain (Fig. 6).The nerve fibers of the retina, representing the axons of the ganglion cells, collect together at the optic disk before passing out of the eye through the orbital bones and into the brain via the optic nerve (the second cranial nerve).
