Table 11.

Descriptive characteristics concerning complete or incomplete data (with complete data indicating that 4 measurements provided an image suitable for analysis); data collected during the initial check. BCVA: best-corrected visual acuity; DM: cone density (1/mm $^{2}$ ); SM: cone spacing ( $μ$ 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).
