Does eccentric fixation alter head movement strategy for smooth pursuit?

Age-related macular degeneration (AMD) can often lead to the loss of the fovea and the surrounding central visual field. This type of vision loss is extremely common (affecting nearly 7% of individuals over 40 in the United states alone, Klein et al. 2011) and can present particular challenges for oculomotor tasks that rely on the high-acuity foveal retina. For certain tasks, individuals develop a new, eccentric fixational area - the preferred retinal locus (PRL). We have previously shown that smooth pursuit is impaired in individuals with macular degeneration, and the degree of impairment
