We compared two pupillometers to assess measurement agreement. Materials &amp; methods: We enrolled 30 subjects and simultaneously measured the pupil diameter and light reflex amplitude with an iPhone pupillometer and a portable infrared pupillometer. We then enrolled 40 additional subjects and made serial measurements with each device. Results: Failure occurred in 30% of attempts made with the iPhone pupillometer compared with 4% of attempts made with the infrared pupillometer (Fisher\u2019s exact p\u00a0=\u00a00.0001). Method comparison of the two devices used simultaneously showed significant disagreement in dynamic measurements. Conclusion: The iPhone pupillometer had poor repeatability and suggests that it is not a practical tool to support clinical decisions. <\/jats:p>","DOI":"10.2217\/cnc-2020-0016","type":"journal-article","created":{"date-parts":[[2020,10,28]],"date-time":"2020-10-28T10:01:55Z","timestamp":1603879315000},"source":"Crossref","is-referenced-by-count":12,"title":["Evaluation of two portable pupillometers to assess clinical utility"],"prefix":"10.63392","volume":"5","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9019-0589","authenticated-orcid":false,"given":"Rachel Eshima","family":"McKay","sequence":"first","affiliation":[{"name":"Department of Anesthesia & Perioperative Care, Professor, University of California\u00a0San Francisco, CA 94143, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5459-5044","authenticated-orcid":false,"given":"Michael A","family":"Kohn","sequence":"additional","affiliation":[{"name":"Department of Epidemiology & Biostatistics, Professor, University of California San Francisco, CA 94143, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elliot S","family":"Schwartz","sequence":"additional","affiliation":[{"name":"Department of Anesthesia & Perioperative Care, Resident in Anesthesia, University of California San Francisco, CA 94143, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0021-5602","authenticated-orcid":false,"given":"Merlin D","family":"Larson","sequence":"additional","affiliation":[{"name":"Department of Anesthesia & Perioperative Care, Professor Emeritus, University of California San Francisco, CA\u00a094143, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"52760","reference":[{"key":"B1","doi-asserted-by":"publisher","DOI":"10.2217\/cnc-2016-0029"},{"key":"B2","doi-asserted-by":"publisher","DOI":"10.1097\/OPX.0000000000001289"},{"key":"B3","doi-asserted-by":"publisher","DOI":"10.3389\/fnint.2017.00006"},{"key":"B4","doi-asserted-by":"publisher","DOI":"10.3171\/2017.12.JNS172386"},{"issue":"3","key":"B5","first-page":"25","volume":"16","author":"Larson M","year":"1989","journal-title":"Anesthesiol.
