First report of the visual defects due to the absence of DJ-1 expression in mice retinas.
DJ-1 KO mice displayed increased b-wave amplitude and cone ERGs, and decreased dc-ERG amplitude.
DJ-1 KO retinas displayed structural changes in the outer plexiform layer, photoreceptors and retinal pigment epithelium.
DJ-1-deficient retinas changes are associated with increased oxidative stress.
