RePer-AGE: Reorganization of Visuo-cognitive Functions Based on Peripheral Vision With Aging
Sponsor: University Hospital, Grenoble
Summary
The RePer-AGE study investigates how central and peripheral vision contribute to visual recognition and how these mechanisms change with normal aging. The study is based on the hypothesis that peripheral vision provides rapid global information that supports visual recognition through predictive mechanisms. Healthy young adults (18-30 years) and older adults (60-85 years) will undergo visual psychophysical testing, ophthalmological examinations, and, for a subset of participants, functional magnetic resonance imaging (fMRI). The results are expected to improve our understanding of age-related changes in visuo-cognitive functions and provide reference data for future studies on age-related visual disorders.

Interventions
Psychophysical visual recognition tasks
Computerized visual recognition tasks assessing the respective contributions of central and peripheral vision to scene recognition and predictive visual processing.
Ophthalmological assessment
Ophthalmological examinations including retinal sensitivity (Humphrey automated perimetry) and low-luminance visual acuity.
Functional magnetic resonance imaging (fMRI)
Functional MRI performed during psychophysical visual recognition tasks to assess brain activity associated with visual recognition and predictive visual processing.
