A centralcanal in the vitreous, corresponding with the site of the arteria hya-loidea, exists in some adult eyes, and may be considered a lymph escape of fluids from the interior of the eye is chiefly by way ofthe anterior chamber and the iris angle, passing through the spaces ofFontana into Schlemms canal and the veins communicating with amount of fluid that passes through the optic nerve is extremelysmall. According to Priestley Smith and Laplat,^ the ratio of the quantityof fluid passing from the eye through the anterior chamber and thepapilla is 50 to 1. It is possible that the iris takes up some of the intra-ocular fluid,^ but the quantity is small. Obstruction to the passage Fig. 13
