Measure
Q4WKS
Aflibercept 2 mg every 4 weeks (defined as every 28 days (+ 7 days) and at least 21 days between injections) through week 48. Following week 48, aflibercept 2 mg every 12 weeks through week 96. If NV or PDR are worse per pre-specified criteria at week 60, or at any study visit thereafter, the subject will be treated every 4 weeks through the end of the study. Aflibercept: Intravitreal injection
Q12WKS
Aflibercept 2 mg every 12-weeks. Subjects will be followed every 4 weeks through week 12, and can be treated if the pre-specified criteria are met. Starting at week 12 if NV or PDR are stable or improved (as assessed by investigator) the subject will be monitored and treated at a 12-week interval through week 48. If NV or PDR are worse per the pre-specified criteria at week 12, or at any study visit thereafter, the subject will be treated monthly through the end of the study. At week 52, aflibercept 2 mg every 4 weeks (defined as 28 days (+ 7 days) and at least 21 days between injections) for subjects with visible retinal non-perfusion. If retinal non-perfusion has completely resolved at week 72, aflibercept every 12 weeks through end of study. For subjects without retinal non-perfusion at week 52, aflibercept 2 mg every 12 weeks through the end of study. Aflibercept: Intravitreal injection

Population: 3 participants that were enrolled dropped out before their Week 4 visit and were replaced in the study. Thus, only 40 subjects of the original 43 were followed and analyzed in the study. Number analyzed at Week 52 and Week 100 differs from overall number analyzed due to inability to analyze images, lost to follow up, or deceased participants.

Changes in self reported visual function utilizing the National Eye Institute Visual Function Questionnaire-25 (NEI VFQ-25) from baseline to week 52 and week 100. The NEI VFQ is a validated measure of patient-reported visual function measured on a scale from 0 (worst function) to 100 (best function).

n=20 Participants
Aflibercept 2 mg every 4 weeks (defined as every 28 days (+ 7 days) and at least 21 days between injections) through week 48. Following week 48, aflibercept 2 mg every 12 weeks through week 96. If NV or PDR are worse per pre-specified criteria at week 60, or at any study visit thereafter, the subject will be treated every 4 weeks through the end of the study. Aflibercept: Intravitreal injection
Q12WKS
n=20 Participants
Aflibercept 2 mg every 12-weeks. Subjects will be followed every 4 weeks through week 12, and can be treated if the pre-specified criteria are met. Starting at week 12 if NV or PDR are stable or improved (as assessed by investigator) the subject will be monitored and treated at a 12-week interval through week 48. If NV or PDR are worse per the pre-specified criteria at week 12, or at any study visit thereafter, the subject will be treated monthly through the end of the study. At week 52, aflibercept 2 mg every 4 weeks (defined as 28 days (+ 7 days) and at least 21 days between injections) for subjects with visible retinal non-perfusion. If retinal non-perfusion has completely resolved at week 72, aflibercept every 12 weeks through end of study. For subjects without retinal non-perfusion at week 52, aflibercept 2 mg every 12 weeks through the end of study. Aflibercept: Intravitreal injection
