Table 8.

Differences in BCVA, DM, SM, and REG changes over a 6-year observation period between males and females: both eyes. BCVA: best corrected visual acuity; DM: cone density (1/${\mathrm{mm}}^2$); SM: cone spacing ($\mathsf{\mu }$m); REG: cone regularity (%); CD: cone dystrophy; CRD: cone–rod dystrophy; STGD: Stargardt disease. The bold was used in all p-Values lower than 0.05 (=with statistical significance).
