Abstract

Many people with vision loss have difficulty locating and identifying familiar objects. There is very little known about the retinal aspects of visual search with vision loss. While eye-trackers have provided information about eye-movements in visual search, only instruments that allow the assessment of visual stimuli position directly on the retina provide information about the retinal aspects of visual search. This in turn documents the relationship between visual search performance and retinal pathology in macular disease. Characteristics of the retinal locus for identification and characteristics of the movement of the retinal locus for identification (saccades) were studied to ascertain their relationship to decreased efficiency in visual search for observers with vision loss.
