PhD thesis :

Deficits, adaptation, and cerebral functional reorganization of central and peripheral visual integration in normal and pathological aging (glaucoma and age-related macular degeneration)

PhD supervision : Carole Peyrin (LPNC / PSM team)

This PhD project aims to investigate the visual and neural mechanisms involved in the processing and integration of information from central and peripheral vision into a coherent whole, in normal vision (healthy young and elderly people) and pathological vision (ophthalmic patients). The project takes advantage of pathologies that selectively impair central (age-related macular degeneration) or peripheral vision (glaucoma) for a better understanding of their respective contribution and their interaction during object and scene perception. In turn, the project investigates perceptual and cognitive visual impairments and residual abilities in healthy visual aging and patients with central or peripheral vision loss (age-related macular degeneration or glaucoma) to assist their adaptation to visual impairment in daily life. The achievement of the project will have a strong theoretical impact for models of visual perception, and a strong clinical impact for health issues that affect many people, particularly in ageing societies.
