Cortical adaptation and plasticity in response to vision loss.
Research at SELAB.
Research in our lab focuses on the understanding of how the visual
system works in people with normal vision, as well as in people with
uncorrectable subnormal vision (visual impairment). Uncorrectable
sub-normal vision can occur as a result of an eye disease
(e.g., age-related macular degeneration, the leading cause of visual
impairment in the US for people over the age of 65), or even in the
absence of an eye disease (amblyopia, or "lazy eye").
In our lab, we combine various non-invasive techniques to study
vision of people with normal or impaired vision. These techniques
include standard (e.g., signal detection theory) and more
contemporary psychophysical methods (e.g., reversed-correlation
method), retinal imaging using Scanning Laser Ophthalmoscope
combined with psychophysical tasks, and functional magnetic brain
The ultimate goals of our research program are to understand the
various limiting factors on visual performance in people with visual
impairment, and to devise methods, devices or rehabilitative
strategies to improve the functional vision of these people,
thereby improving their quality of life.
