Visual Acuity: Number of Participants Keeping a BCVA Score Gain ≥10 Letters Secondary · Baseline, Month 3, 6, 8 and 11

Best-Corrected Visual Acuity (BCVA) letters was measured using Early Treatment Diabetic Retinopathy Study (EDTRS)-like chart while participants were in a sitting position at a testing distance of 4 meters. The range of EDTRS is 0 to 100 letters. A positive change from baseline of BCVA indicates improvement. Best value on the scale 100, worst 0. The number of participants maintaining ≥10 letters gains in BCVA (compared to the baseline BCVA \[Day 0\]) value for each visit from Month 3 onwards were reported.

Visual Acuity: Number of Participants With a BCVA Loss ≥15 Letters at Months 8 and 11 Compared to Month 6 in the Study Eye. Secondary · Months 6, 8 and 11

Best-Corrected Visual Acuity (BCVA) letters were measured using Early Treatment Diabetic Retinopathy Study (EDTRS)-like chart while participants were in a sitting position at a testing distance of 4 meters. The range of EDTRS is 0 to 100 letters. A positive change from baseline of BCVA indicates improvement. Best value on the scale 100, worst 0. Number of participants presenting with a ≥15 letter loss in BCVA (compared to the value observed at 6 months) and leading to a treatment change (Rescue Group) for month 8 and 11 were analyzed.

Visual Acuity : Change of BCVA From Baseline in the Study Eye (ETDRS) Secondary · Baseline, months 1, 2, 3, 4, 5, 6, 8 and 11

Best-Corrected Visual Acuity (BCVA) letters was measured using Early Treatment Diabetic Retinopathy Study (EDTRS)-like chart while participants were in a sitting position at a testing distance of 4 meters. The range of EDTRS is 0 to 100 letters. A positive change from baseline of BCVA indicates improvement. Best value on the scale 100, worst 0. The mean variation in BCVA was compared to the baseline BCVA value \[Day 0\] over a period of 24 months for patients in the Main Group.

Central Retinal Thickness : Change of Log OCT From Baseline in the Study Eye Secondary · Baseline, months 1, 2, 3, 4, 5, 6, 8 and 11

Retinal thickness is assessed by optical coherence tomography (OCT) in the study eye. The retina is the light-sensitive part of the eye. OCT is a laser-based, noninvasive, diagnostic system providing high-resolution, three-dimensional images of the retina. A negative mean change from baseline indicates an improvement and a positive mean change from baseline indicates a worsening.The absolute variations of the Central Retinal Thickness (CRT) was measured using a Spectral Domain-Optical Coherence Tomography (SD-OCT) at each visit. Values were calculated as a log OCT (=log\[CRT/200\]).
