Representative photos for 3 macaques of the blue light exposure area over the study duration. The prestudy image for macaque B is unfortunately unavailable. Clinical improvement was most pronounced in macaque D as demonstrated by decreased erythema. Macaque L did not show clinical improvement as demonstrated by a sustained granulation tissue response. Due to the diversity of cranial implant morphologies for animals enrolled on study, we were unable to create a quantitative scoring system.
