Observational study shows enhanced retinal clearance of amyloid in mice via light flicker, suggesting a new therapeutic approach.
We observed that 40-Hz light flicker enhances retinal microglial clearance of Aβ oligomers by upregulating MHC-II expression. These findings support 40-Hz light flicker as a non-invasive therapeutic strategy for age-related retinal disorders by promoting metabolic waste clearance.
