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). Supervision : Carole Peyrin (LPNC / PSM team)

I am interested in the characteristics of peripheral vision, such as visual crowding, and in the visual and neural mechanisms involved in the processing and integration of information from central and peripheral vision into a coherent whole. This PhD project aims to investigate these questions in normal vision (healthy youg and elderly people) and pathological vision (ophtalmic 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. We are currently working at a better understanding of the residual central vision in people with glaucoma.
