Synaptophysin Immunoreactivity (IMAGE) Neural Regeneration Research Caption Synaptophysin immunoreactivity was still detectable across the entire inner plexiform layer and the inner plexiform layer had clearly thinned following 3 days of high intraocular pressure induction. In the outer plexiform layer, after 3 days of high intraocular pressure induction, synaptophysin immunoreactivity had spread and extended into the inner part of the outer nuclear layer.
