Recent evidence shows that the PLR and PIPR can provide non-invasive, objective markers of age-related retinal and optic nerve disease; however there is no consensus on the effects of healthy ageing or refractive error on the ipRGC mediated pupil function. Here we isolated melanopsin contributions to the pupil control pathway in 59 human participants with no ocular pathology across a range of ages and refractive errors. We show that there is no effect of age or refractive error on ipRGC inputs to the human pupil control pathway. The stability of the ipRGC mediated pupil response across the human lifespan provides a functional correlate of their robustness observed during ageing in rodent models.<\/jats:p>","DOI":"10.1038\/srep17610","type":"journal-article","created":{"date-parts":[[2015,12,1]],"date-time":"2015-12-01T05:22:38Z","timestamp":1448947358000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":70,"title":["Effect of Age and Refractive Error on the Melanopsin Mediated Post-Illumination Pupil Response (PIPR)"],"prefix":"10.1038","volume":"5","author":[{"given":"Prakash","family":"Adhikari","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Candice A.","family":"Pearson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexandra M.","family":"Anderson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrew J.","family":"Zele","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Beatrix","family":"Feigl","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2015,12,1]]},"reference":[{"key":"BFsrep17610_CR1","doi-asserted-by":"publisher","first-page":"600","DOI":"10.1523\/JNEUROSCI.20-02-00600.2000","volume":"20","author":"I Provencio","year":"2000","unstructured":"Provencio, I. et al.
