There is evidence that some of the circadian photoreceptors, the intrinsically photosensitive
retinal ganglion cells (ipRGCs), project directly to the amygdala, an area of the brain
implicated in PTSD. Thus, a self-administered morning light treatment at home (shifts clock
earlier and stimulates ipRGCs) may be a potentially efficacious adjunctive strategy for
reducing PTSD symptoms. This study will test a 4 week daily 1 hour morning light treatment
(active vs placebo) in individuals with PTSD. Outcome measures include measures of PTSD and
depression.
