Although the eye of the cat has been used extensively in ophthalmic research, certain anatomical details have not received warranted attention. In this study a description of the cat retinal blood vessels and fundus will be given. The tapetum lucidum will be described.
Leber1 has classified the eye of placentals on the basis of the area of the retina supplied directly by retinal vessels. Thus the cat retina is holangiotic, that is, one in which the entire inner retina receives its blood supply directly from the retinal vessels, while that of the rabbit is merangiotic, or one in which only part of the retina is supplied directly by vessels, which are confined to the medullated wings on either side of the optic papilla. In the cat there are 3 main retinal arterioles with corresponding veins. The arterioles do not derive from a central retinal artery but are 3 separate
