Comparative StudyOptic nerve and peripapillary choroidal microvasculature of the rat eye.
To investigate the three-dimensional microvascular anatomy of the optic nerve and peripapillary choroid in the rat eye. ⋯ The findings illustrate vascular anatomic differences in optic nerve and peripapillary choroidal microcirculation between rat and human. In rats, the peripapillary choroid plays a significant role in both blood supply and venous drainage of the optic nerve head. The central retinal artery also contributes to the optic nerve head circulation.
