Iris front view

Vessels and Nerves

The arteries of the iris are derived from the long and anterior ciliary arteries, and from the vessèls of the ciliary processes (see p. 571). Each of the two long ciliary arteries, having reached the attached margin of the iris, divides into an upper and lower branch; these anastomose with corresponding branches from the opposite side and thus encircle the iris; into this vascular circle (circulus arteriosus major) the anterior ciliary arteries pour their blood, and from it vessels converge to the free margin of the iris, and there communicate and form a second circle (circulus arteriosus minor) (Figs. 877 and 878).
