Table 4.
Changes in adaptive optics parameters between the initial (2015) and follow-up (2021) checks. BCVA: best corrected visual acuity; DM: cone density (1/mm2); SM: cone spacing (μm); 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).
