Clinical appearance of the hyaloid artery system in the newborn rhesus monkey.
Fifteen healthy newborn rhesus monkeys (Macaca mulatta) were given funduscopic examinations as part of a screening process before utilization in a research project. The hyaloid vasculature, a system that supplies blood to the embryonic ocular structures, was observed in each subject and was noted to regress clinically at two to three weeks of age. Although the phenomenon has been described morphologically in the literature, its clinical appearance has not been illustrated for the primate clinician.
