Presentation Description :
When the fovea has been lost in both eyes, people use an alternative viewing strategy, directing a peripheral retinal region to the object of interest, that is known as the preferred retinal locus (PRL). Vision with a PRL is worse than with a fovea. Worse because of reduced resolution, other limitations of peripheral vision (e.g. crowding) and eye movement control. Does vision with a PRL improve with experience or training? To improve our understanding, can the PRL be simulated? The PRL is usually determined using a fixation task, but is that PRL used for tasks? What happens to the PRL when the retinal lesion expands and encroaches on that location?
