简介：
Overview
This protocol provides both in vivo and ex vivo measures for visualizing and characterizing the hyaloid vasculature within the eye as a useful experimental model for studying vascular regression. The technique combines in vivo longitudinal observation of hyaloid vessels in live mice and ex vivo visualization and accurate quantification of dissected whole hyaloid vessels.
