Relationships between LD and ocular biometric parameters were then investigated. Eyes with AL\u2009\u2265\u200928\u2009mm were defined as eyes with extreme myopia, and eyes with AL\u2009&amp;lt;\u200928\u2009mm were defined as eyes without extreme myopia.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 194 eyes from 194 subjects were included. The mean LD was 9.58\u2009\u00b1\u20090.49\u2009mm, ranging from 8.60 to 10.96\u2009mm. According to univariate analysis, larger LD was associated with elder age, male gender, larger WTW, ACD and ASL (all <jats:italic>p<\/jats:italic>\u2009&amp;lt;\u20090.05). Meanwhile, the LD was positively correlated with AL in eyes without extreme myopia (p\u2009&amp;lt;\u20090.05), but not in eyes with extreme myopia (<jats:italic>p<\/jats:italic>\u2009&amp;gt;\u20090.05). Backward stepwise regressions revealed that a larger LD was associated with larger WTW, ASL and AL in eyes without extreme myopia (all <jats:italic>p<\/jats:italic>\u2009&amp;lt;\u20090.05), while ASL
