Aqueous drainage in the dog.
The anatomical features of the iridocorneal angle and its associated structures are described and their role in the drainage of aqueous in the dog discussed. Anterior segment material from 126 dogs of various ages and many breeds was examined by light and electron microscopy, the results confirming that the elements of bulk aqueous drainage in this species are essentially the same as those of the primate eye. In particular, the demonstration of an avascular aqueous plexus lined with a vacuolating endothelium as an analogue of the primate Schlemm's canal has indicated that the theory of capillary drainage of aqueous is no longer tenable for the dog.
