Stereopsis – deriving information about distance by comparing views from two eyes – is widespread in vertebrates but so far known in only class of invertebrates, the praying mantids. Understanding…
Dual sensory impairment (DSI) refers to combined vision and hearing impairment. DSI concerns a large population and its prevalence increases drastically with age. In the US, it is estimated that 40%…
Macular Degeneration (MD) represents the leading cause of visual impairment in the Western World. Late-stage MD eventually leads to the development of a central region of blindness (scotoma), which…
We have developed robust and objective measures that do not depend upon the young patient’s cooperation or provider’s assessments of visual acuity and strabismus angle and quantifies the entire…
The psychophysical and oculomotor literatures have long proposed that stereoscopic vision is served by multiple underlying subsystems. The subsystems are usually construed in terms of dichotomies, e.g…
I will discuss human fMRI and MEG studies of binocular rivalry, including some recent work on individual differences. Alternations between bistable percepts provide a powerful platform to study visual…
CVI is now the commonest cause of bilateral visual functional loss in children with a visual impairment and the prevalence is increasing worldwide. CVI is a brain-based condition resulting usually…
