Dissection of eye
Vascular tunic of right eye
The sclera and cornea have been cut away on the medial side of a right eye to display the anterior chamber (7), iris(6), ciliary body(10) and outer surface of the choroid. Although none of the vessels has been injected, the branches of the superior and inferior medial vorticose veins (13,18) are clearly visible. The long posterior ciliary artery (17) was cut across in the resection of the sclera but its course can be traced nearly to the ciliary body. The distribution of the short posterior ciliary arteries is represented by the vessel at 14.
