Participants received 2mg Intravitreal aflibercept injection (IAI) (EYLEA, VEGF Trap-Eye, BAY86-5321) every 4 weeks (2Q4).
Participants received 2mg Intravitreal aflibercept injection (IAI) (EYLEA, VEGF Trap-Eye, BAY86-5321) every 4 weeks for 5 visits followed by injections every 8 weeks (2Q8).
Participants received laser treatment at baseline and as needed at visits at which laser retreatment criteria were met, but no more frequently than every 12 weeks.

Change From Baseline in Best Corrected Visual Acuity (BCVA) as Measured by Early Treatment Diabetic Retinopathy Study (ETDRS) Letter Score at Week 52 - Last Observation Carried Forward (LOCF)
Visual function of the study eye was assessed using the ETDRS protocol, which is a widely accepted international standard for macular laser photocoagulation treatment. A higher score represents better functioning. LOCF censored measurements after additional treatment.
Time frame: Baseline up to week 52
Percentage of Participants Who Gained at Least 10 Letters in BCVA as Measured by ETDRS Letter Score Compared With Baseline at Week 52 - LOCF
Visual function of the study eye was assessed using the ETDRS protocol. A higher score represents better functioning.
Time frame: Baseline up to week 52
Percentage of Participants Who Gained at Least 15 Letters in BCVA as Measured by ETDRS Letter Score Compared With Baseline at Week 52 - LOCF
Visual function of the study eye was assessed using the ETDRS protocol. A higher score represents better functioning.
Time frame: Baseline up to week 52
Percentage of Participants With a Greater Than Equal (>=) Two-step Improvement From Baseline in the ETDRS Diabetic Retinopathy Severity Score (DRSS) as Assessed by Fundus Photography (FP) at Week 52 - LOCF
ETDRS DRSS: None (level 10); Mild to moderate nonproliferative diabetic retinopathy (DR) (levels 14, 15, 20, 35, and 43); Moderately severe/severe nonproliferative DR (levels 47 and 53); Mild/moderate/high-risk/advanced proliferative DR (levels 61, 65, 71,75, 81, and 85)
Time frame: Baseline up to week 52
Change From Baseline in Central Retinal Thickness (CRT) at Week 52 as Assessed on Optical Coherence Tomography (OCT) - LOCF
CRT was assessed using spectral domain optical coherence tomography (SD-OCT), a non-invasive diagnostic system providing high-resolution imaging sections of the retina. SD-OCT was performed in the study eye after pupil dilation. A negative change from Baseline indicated improvement.

Change From Baseline in National Eye Institute 25-item Visual Function Questionnaire (NEI VFQ-25) Near Activities Subscale at Week 52 - LOCF
The NEI VFQ-25 total score ranges from 0-100 with a score of 0 being the worst outcome and 100 being the best outcome. The NEI VFQ questionnaire is organized as a collection of subscales that are all scored from 0-100. Near activities are defined as reading ordinary print in newspapers, performing work or hobbies requiring near vision, or finding something on a crowded shelf.
Time frame: Baseline up to week 52
Change From Baseline in National Eye Institute 25-item Visual Function Questionnaire (NEI VFQ-25) Distance Activities Subscale at Week 52 - LOCF
The NEI VFQ-25 total score ranges from 0-100 with a score of 0 being the worst outcome and 100 being the best outcome. The NEI VFQ questionnaire is organized as a collection of subscales that are all scored from 0-100. Distance activities are defined as reading street signs or names on stores, and going down stairs, steps, or curbs.
Time frame: Baseline up to week 52
