  1. P-value * is calculated by Chi-Square Test, P-value ** is calculated by two independent sample T-Test
  2. CMT, central macular thickness; SFCT, sub-fovea choroidal thickness; HF, hyperreflective foci; DRIL, disorganization of the retinal inner layers; ELM, external limiting membrane; FE, fellow eye
