Abstract

Recently a procedure was presented for long-term direct determinations of the blood flow from the uvea in rabbits.1 It seemed desirable to find such a procedure also in cats, since the vasoregulation in this species in general is regarded as more similar to that found in man than that studied in rabbits.

The procedure found convenient with rabbits was to open one of the 4 vortex veins, cannulate it, and determine the flow from the cannula. If certain requirements were fulfilled, the flow through the whole uvea could be determined as 4 times the flow from the cannula.

In cats, it was clear from the anatomy of the vessels draining the uvea that such a procedure could not be used, since in this species there are anterior ciliary veins of such a magnitude that the flow through them cannot be neglected.

The following description of the vessels draining the
