Correlation between DM change over a 6-year observation and initial parameters BCVA, DM, SM, REG, and age; BCVA change, SM change, and REG change. Initial BCVA: best corrected visual acuity at initial check (2015). Initial DM: cone density at initial check (2015) (1/${\mathrm{mm}}^2$). Initial SM: cone spacing at initial check (2015) ($\mathsf{\mu }\mathrm{m}$). Initial REG: cone regularity at initial check (2015) (%). BCVA change: difference in best corrected visual acuity between the initial check and follow-up. SM change: difference in cone spacing between the initial check and follow-up ($\mathsf{\mu }\mathrm{m}$). REG change: difference in cone regularity between the initial check and follow-up (%). The bold was used in all p-Values lower than 0.05 (=with statistical significance).
