  1. AL, axial length.
  2. P values were yielded by partial correlation analysis (Pearson correlation) after adjusting for sex to evaluate the effect of age on macular thickness in each other group (r = partial correlation coefficients).
  3. *Bold values indicate statistically significant differences (P < 0.05).
