Decline of vertical gaze and convergence with aging.

abstract：:One of the problems associated with using random-source dogs to study in vivo vascular responses is their unknown background. Since aging is known to influence vascular responses, unknown variations in age could influence experimental results. The vast majority of aging studies examine arteries in vitro. This study wa...
