Significant increases were found among students in junior high school and beyond, patients with myopia, patients with Bielschowsky type AACE, and patients with basic esotropia (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.0001 for all). We compared two age groups, elementary school students and below versus junior high school students and above, and found that the rate of increase was significantly higher in the junior high school students and above (estimate, 1.951; <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.0001), and the non-myopia group and myopia group and found that the rate of increase was significantly higher in the myopia group (estimate, 1.891; <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.0001). Excessive use of smartphones was confirmed in 82 of 133 patients, and the rate of the increase in the number of patients with AACE was significantly greater among patients with than without excessive use of smartphones (estimate, 1.098; <jats:italic>p<\/jats:italic>\u2009=\u20090.0009).<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>This study confirmed a significant increase in the number of patients with AACE in recent years.
