The present study compared measurements of the amplitude of accommodation (\n AA<\/jats:styled-content>\n ) obtained using this technique with two subjective methods (modified push\u2010down and minus lens). Additionally, the expected ranges for\n AA<\/jats:styled-content>\n when measured by\n DR<\/jats:styled-content>\n were determined.\n <\/jats:p>\n <\/jats:sec>\n \n Method<\/jats:title>\n \n AA<\/jats:styled-content>\n was measured in 1298 subjects between 5 and 60\u00a0years of age using the three techniques described above. Subjects were grouped into 5\u2010year bins, and a descriptive univariate analysis of the data performed. Goodness\u2010of fit plots were constructed to examine the overall model fit. Centile curves were calculated from the final model.\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Mean values of\n AA<\/jats:styled-content>\n obtained using\n DR<\/jats:styled-content>\n were significantly lower than for the two subjective techniques. For the\n DR<\/jats:styled-content>\n findings, no significant change was observed between 5 and 19\u00a0years of age (mean\n AA<\/jats:styled-content>\n \u00a0=\u00a08.3\u00a0D) and between 45 and 60\u00a0years of age (mean\n AA<\/jats:styled-content>\n \u00a0=\u00a00.6\u00a0D).\n AA<\/jats:styled-content>\n values as a function of age were best fit by the polynomial regression equation: log\n AA<\/jats:styled-content>\n \u00a0=\u00a01.93\u00a0+\u00a00.49(age)\u00a0\u2212\u00a00.19(age)\n 2<\/jats:sup>\n .\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n \n Measurements of\n AA<\/jats:styled-content>\n determined using\n DR<\/jats:styled-content>\n are significantly lower than the normative subjective findings published previously. This difference is at least partly due to the depth\u2010of\u2010field of the eye. These norms markedly overestimate accommodative responsivity.\n DR<\/jats:styled-content>\n provides a simple technique for quantifying accommodation in the clinical setting.\n <\/jats:p>\n <\/jats:sec>","DOI":"10.1111\/opo.12244","type":"journal-article","created":{"date-parts":[[2015,9,10]],"date-time":"2015-09-10T09:52:10Z","timestamp":1441878730000},"page":"5-12","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":43,"title":["Age and the amplitude of accommodation measured using dynamic retinoscopy"],"prefix":"10.1007","volume":"36","author":[{"given":"Alejandro","family":"Le\u00f3n","sequence":"first","affiliation":[{"name":"Universidad de la Salle Bogot\u00e1 D.
