  1. Results are presented as mean (95% confidence interval) or percentage. Race was compared using a chi-squared test. Continuous variables were compared using ANOVA (for age) or linear mixed models (for eye level data). No myopia: AL ≤ 24.0 mm; Mild myopia: AL: > 24 mm and ≤ 26.0 mm; High myopia: AL > 26.0 mm.
  2. Missing 66a, 14b, 2c, and 28d values.
  3. 1No versus Mild Myopia p < 0.05; 2No versus High Myopia p < 0.05; 3Mild versus High Myopia p < 0.05.
  4. AL, axial length; BMO, Bruch’s membrane opening; CCT, central corneal thickness; IOP (intraocular pressure); SE, spherical equivalent; VF MD, visual field mean deviation.
