A supplement to the cat schematic eye

Abstract The uniocular and binocular fields of view of the cat eye were calculated by Vakkur and Bishop (1963) from their schematic eye but still lack confirmation by direct measurement. In the schematic eye these authors develop only the fields of view determined by the dioptric apparatus. Their assumption that the extent of the retina is not a limiting factor is shown to be invalid f or the cat so that the animal possesses differentiable optical and retinal fields. Measurements supplementary to the cat schematic eye are presented including the requisite extents of the optical and retinal, uniocular and binocular, fields as well as more information about the relative compression of the peripheral retinal image.
