An experimental group of 43 patients was measured with the Maddox Wing test for heterophoria. Exophoria was greater 1\u00bd, 2\u00bd, and 3\u00bd hr. after the end of general anesthesia than at baseline level. Data for a control group of 25 did not vary on the Maddox Wing over four hours. The baseline level was not different between the two groups, so heterophoria as measured with the Maddox Wing can be used to evaluate subjects\u2019 alertness during recovery from general anesthesia.<\/jats:p>","DOI":"10.1177\/00315125890693-153","type":"journal-article","created":{"date-parts":[[2019,2,28]],"date-time":"2019-02-28T04:21:27Z","timestamp":1551327687000},"page":"991-996","source":"Crossref","is-referenced-by-count":0,"title":["Heterophoria as a Measure of Subjects\u2019 Alertness during Recovery from General Anesthesia"],"prefix":"10.1177","volume":"69","author":[{"given":"J.
