Fig. 46-10. The blood supply of the eye. The short posterior ciliary arteries give rise to numerous capillaries (the choriocapillaris, not shown here) that supply the external part of the retina. The internal part is supplied by the branches of the central artery of the retina, which do not anastomose with each other. At the front of the eye, the posterior conjunctival vessels become dilated in conjunctivitis, whereas the anterior ciliary vessels become dilated in inflammation of the cornea, iris, or ciliary body. m, marginal arcade, and p, peripheral arcade of eyelid. S.V., sinus venousus sclerae, the canal described by Schlemm. It transmits aqueous humor to the ciliary veins. Click for high resolution image.
