Ocular microcirculation. Scanning electron microscopic study

A simple vascular casting technique utilizing a low-viscosity plastic was used to study the three-dimensional ocular microcirculation of the cat eye. Vascular arrangements in different anatomic areas of the eye, i.e., iris, ciliary body, retina, optic nerve, and choroid, were clearly elucidated by scanning electron microscopy. This modified technique is described in detail, and scanning electron micrographs are presented to illustrate the reliable results.
