The blood supply to the lateral geniculate body (LGB) was studied carefully by Abbie1 and later by François et al.2,3 Abbie studied both "untreated" brains and brains which had had colored gelatin injected into the cerebral vessels. To study the intrastitial blood distribution he examined thin slices of the LGB, and his major observations were as follows:
The intrastitial blood supply to the LGB is derived from vessels which lie on the ventral surface of the LGB, and while most of these enter and end within the LGB, there are some which pass through and accompany the fibers of the optic radiations;
One vessel gives branches to corresponding areas of adjoining laminae;
The number of terminal twigs to the intermediate quadrant of the LGB (macular area) is much greater than that to the more medial and lateral segments (peripheral retina) of the LGB.
From these observations Abbie was
