Mean Change From Baseline to Day 28 in Visual Acuity
Best-correct visual acuity (BCVA) was assessed using Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity testing charts. The visual function of the study eye was assessed using the ETDRS protocol. ETDRS letters score can be calculated when 20 or more letters are read correctly at 4.0 meters (m); the visual acuity letter score is equal to the total number of letters read correctly at 4.0 m plus 30. If less than 20 letters are read correctly at 4.0 m, the visual acuity letter score is equal to the total number of letters read correctly at 4.0 m (number of letters recorded on line 1.0), plus the total number of letters read correctly at 1.0 m in the first six lines. The score ranges from 0-100 where a higher score represents better visual functioning. The change from baseline was calculated by subtracting baseline value from post-baseline value.
Time frame: Baseline and Day 28
Population: Pharmacodynamics (PD) analysis set included all participants from the modified Safety population who had at least 1 post-baseline non-missing PD assessment.

Number of Participants With Adverse Events (AEs), Serious Adverse Events (SAEs), Ocular and Non-ocular AEs and SAEs
An AE is defined as any untoward medical occurrence in a participant or clinical investigation participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a medicinal product. An SAE is defined as any untoward medical occurrence that, at any dose, results in death, is life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, is a congenital anomaly/birth defect, may jeopardize the participant or require medical or surgical intervention to prevent one of the other outcomes listed in the definition above, or is an event of possible drug-induced liver injury. Data has been presented for number of participants with ocular and non-ocular AEs and SAEs.
