Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Other - Aflibercept Injection (EYLEA, VEGF Trap-Eye, BAY86-5321)
Other interventions - Sham treatment

Experimental: Aflibercept Injection (EYLEA, VEGF Trap-Eye, BAY86-5321) - Participants received a 2 mg dose of Intravitreal Aflibercept Injection (IAI) administered every 4 weeks from Day 1 through Week 20, later as often as every 4 weeks depending on the study retreatment criteria from Week 24 through Week 48. Follow-up phase: Participants on IAI, who continued the study, received 2 mg dose of IAI depending on the study retreatment criteria at Week 60 and 68.

Sham comparator: Sham treatment - Participants received sham treatment administered every 4 weeks from Day 1 through Week 52. Follow-up phase: Participants on sham treatment, who switched to Intravitreal Aflibercept Injection (IAI), received a 2 mg dose of IAI at week 52 and depending on the study retreatment criteria at Week 60 and 68.


Treatment: Other: Aflibercept Injection (EYLEA, VEGF Trap-Eye, BAY86-5321)
Intravitreal injection. Weeks 0 to 20 of Aflibercept Injection every 4 weeks; Weeks 24 to 52 every 4 weeks PRN (pro re nata, on demand); plus additional on Week 60 and 68.

Other interventions: Sham treatment
Sham treatment. Weeks 0 to 52 sham treatment every 4 weeks; plus additional on Week 60 and 68.
