[Arterial vascularization of the musculi rectus verticalis and obliquus oculi (author's transl)]

In a recent article, we described arterial vascularization of the musculi rectus medialis and lateralis, using a radiological technique. We have now studied, in the cadaver, arterial vascularization of the musculi obliquus and rectus verticalis, from 30 new orbital contents. The posterior two thirds of the ocular face of each muscle and its edges are particularly rich in vascular inlets. The musculus rectus superior often has one pedicle only, in the shape of a tuning fork, stretched over nearly the whole length of the muscle. The musculus rectus inferior often has only a single central pedicle clearly visible in the anterior third of the muscle only. The musculus obliquus superior has two vascular sources which form one or two central axes. The arrangement of the arterioles in the musculus obliquus inferior is always the same, the main point of entry being located in the middle of the posterior face of the muscle. The anterior eiliary arteries in arising the two musculi rectus verticalis, are particularly large.
