The human visual system comprises multiple structurally and functionally specialized pathways with differing vulnerabilities across the lifespan. Assessing the integrity of these pathways is a critical component of clinical practice, where it is used to diagnose and monitor the progression or remediation of eye disease. In basic research, vision screening is used to quantify low-level sensory deficits and higher-level perceptual processing deficits. Comprehensive visual assessment requires the administration of multiple specialized tests, each of which typically requires the use of specialized stimuli, equipment and tasks that participants must be trained to perform. This requires significant resources to administer and can place a heavy burden on patients. These factors can impact performance and confound attention, learning and memory effects with visual function deficits. These pressures have led to compromises in the number and duration of tests that are administered, with the risk that vision assessment is inaccurate (due to noisy or under-constrained data) or incomplete (because only a subset of tests is administered). In this talk, Bex will describe a range of techniques my lab has developed that increase the speed, efficiency and accessibility of vision assessment.
