numerous branches extend to the ciliary processes (3) and to the iris (4). Near the 

 pupillary border of the iris, the arteries form an incomplete ring, the circulus iridis 

 minor. 



3. The anterior ciliary arteries proceed from those supplying the recti muscles, 

 penetrate the sclera near the cornea, and in part join the circulus iridis major, in part 

 supply the ciliary muscle, and in part through recurrent branches, connect with the

lamina choriocapillaris. Before penetrating the sclera, the anterior ciliary arteries 

 give off posterior branches for the anterior half of the sclera, and anterior branches for 

 the conjunctiva bulbi and the corneal border. The cornea itself is without vessels, 

 but at its border, between the anterior lamellae of the substantia propria, there are 

 terminal loops.
