Meanwhile, it is unclear whether the B\/YP learning effect is influenced by age and refraction.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Twenty healthy subjects, 26 OHT and 14 primary open angle glaucoma (POAG) patients, underwent three full-threshold B\/YP tests at intervals of 7 to 21 days. Of the 60 subjects, 38 had no previous W\/WP experiences, 22 had previous W\/WP experiences for at least two times. The parameters investigated to detect a learning effect were the perimetric indices and the test duration (TD).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Learning effects were demonstrated for mean deviation (MD), pattern standard deviation (PSD), short-term fluctuation (SF), and TD. Significant differences were found between the MD, PSD, SF, and TD of the first test and those of the second and third tests (p&lt;0.05). However, no difference was found between those parameters of the second and third tests. No statistically significant differences were noted in terms of MD\n                      <jats:sub>1st-2nd<\/jats:sub>\n                      , MD\n                      <jats:sub>1st-3rd<\/jats:sub>\n                      , PSD\n                      <jats:sub>1st-nd<\/jats:sub>\n                      , PSD\n                      <jats:sub>1st-3rd<\/jats:sub>\n                      , TD\n                      <jats:sub>1st-2nd<\/jats:sub>\n                      , and TD\n                      <jats:sub>1st-3rd<\/jats:sub>\n                      between the group with W\/WP experience and the group without previous W\/WP experience (p&gt;0.05).
