Calculated by Mixed regression model taking into account multiple eyes for the same subjects. BCVA= best corrected visual acuity for far distance measured by early treatment diabetic retinopathy study (ETDRS) charts at 4 meters in logarithm of the minimum angle of resolution (logMAR) units; close-up visus = visual acuity for near vision in points (Pts) measured by magnifying system and necessary magnification, X = necessary magnification; Retinal sensitivity = measured by microperimetry (MY) in decibel (dB); SD = standard deviation.
