Measurements from the right eye were made for 0\u2009D and 6\u2009D accommodation stimuli for \u00b130\u00b0 horizontal visual field\/retinal locations in 10\u00b0 steps. Valid eye length and choroidal thickness measurements were obtained for 37 and 47 participants, respectively, and both measures were taken for 31 participants. 2.5% phenylephrine was instilled to dilate the pupils. Participants turned their eyes, without head movement, to fixate targets and to make the target \u2018as clear as possible\u2019 during measurements. Correction was made for the influence of lens thickness changing at different peripheral angles. Choroidal thickness was measured with a spectral\u2010domain\u2010Optical Coherence Tomographer. For peripheral images, the internal cross target on the capture screen was moved from the centre to 17.25\u00b0 nasal\/temporal positions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      In accordance with previous literature, eye length increased with accommodation. The greatest change (mean\u2009\u00b1\u2009SD) of 41\u2009\u00b1\u200917\u2009\u03bcm occurred at the centre, with a mean change across the locations of 33\u2009\u03bcm. There were no significant differences between emmetropes and myopes. Choroidal thickness decreased with accommodation, with changes being about two\u2010thirds of those occurring for eye length. The greatest change of \u221230\u2009\u00b1\u20091\u00a0\u03bcm occurred at the centre, with a mean change of \u221221\u2009\u03bcm. Greater choroidal thinning occurred for myopes than for emmetropes (23\u2009\u00b1\u200911 vs. 17\u2009\u00b1\u20098\u00a0\u03bcm,\n                      <jats:italic>p<\/jats:italic>\n                      \u00a0=\u00a00.02).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>With accommodation, eye length increased and the choroid thinned, at both central and peripheral positions.
