Vascularization of the Optic Pathway
TEis problem has been of only moderate interest to research workers, and publications and monographs on the subject have been sporadic, though a few well-known names must be cited here (Leber, 1865a, b, 1872, 1903; Magitot, 1908, 1947; Behr, 1935; Wolff, 1939, 1940, 1948). The findings being very diverse, it seemed appropriate to try to find experimentally the normal vascular anatomy of the opt...
متن کاملVascularization of the Optic Pathway*
WHEREAS from the myelo-architectonic point of view the chiasma is merely an organ of transit, this is not so from the vascular point of view; there seems to be a partial dissociation between the myelo-architecture and the angio-architecture. The vascularization of the chiasma has been investigated on the basis of 22 human specimens. The techniques used (dissection after fixation in 10 per cent....
متن کاملTumour of the optic chiasma.
Tumours arising in the small area at the base of the brain between the optic chiasma and cerebral peduncles are common and include meningiomas, suprasellar and pituitary neoplasms, aneurysm of the circle of Willis, and chiasmal arachnoiditis with cyst formation. Tumours arising in the optic chiasma and nerve sheaths, however, are very uncommon. In all these conditions, visual symptoms may obtru...
متن کاملGlioma of Chiasma and Optic Nerve.
IN a case of orbital optic nerve glioma without intracranial extension, Davis (1940) removed the tumour through a skin incision at the lower orbital margin, cutting the optic nerve near the apex of the orbit and behind the globe and thus retaining the eye. Verhoeff (1922) found that, even when the tumour was partially removed by the orbital route leaving some intracranial portion, no orbital re...
متن کاملThe anatomy of the optic chiasma and heteronymous hemianopia.
The gross anatomy of the optic nerves and chiasma has been studied, and differences in the tension in the crossed and uncrossed fibres after chiasmal displacement have been investigated. The anterior and posterior attachments of the medial and lateral fibres of the nerves have been studied. The chiasma has been dissected under low power microscopy and a three dimensional picture of it developed...
