Optic nerve head microvasculature of the rabbit eye.

摘要: Vascular luminal castings of rabbit eyes were microdissected and studied with scanning electron microscopy to elucidate the three-dimensional angioarchitecture optic nerve head. Using sequential microdissection, an incomplete arterial circle was identified as terminal branches two three short posterior ciliary arteries around Several recurrent from form a pial network. This system supplies head microvasculature receives numerous venules them. The only large vessel enter is central retinal artery that has few within provides several at surface disc. Moderately vessels connect vascular layers Few arterioles arise choroid; however, there are small number capillary venous connections between These results indicate principal blood supply derived by circle. contribute vasculature also plays significant role in both drainage
