Development of a preferred retinal locus in response to a simulated central scotoma: visuomotor adaptation or strategy?
Patients with central vision loss (scotoma) often rely on a location outside the scotoma for seeing, the preferred retinal locus (PRL). We investigated whether the development of a PRL in response to a simulated scotoma in normally sighted individuals is the result of oculomotor adaptation, as is the case in patients with a real scotoma. We used a gaze-contingent paradigm to occlude the central vision of normally sighted subjects while they performed a visual task.
