23. Only 1 functional eye even if that eye is otherwise eligible for the study
24. Ocular media of insufficient quality to obtain fundus and OCT images

30. Renal failure requiring dialysis or renal transplant
31. History of other disease, metabolic dysfunction, physical examination finding, or clinical laboratory finding giving reasonable suspicion of a disease or condition that contraindicates the use an investigational drug, might affect interpretation of the results of the study, or renders the subject at high risk for treatment complications.
32. Pregnant or breast-feeding women. In addition, to prevent exposure during pregnancy female subjects, male subjects, and their partners must agree to the following.
33. Women of childbearing potential with either a positive pregnancy test result or no pregnancy test at baseline are excluded. Postmenopausal women must be amenorrheic for at least 12 months in order not to be considered of child bearing potential.

E.5 End points |
E.5.1 | Primary end point(s) |
The primary endpoint is the change from baseline of BCVA in ETDRS letters score at Week 52 compared to baseline (Day 1). |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
Comparisons between each of the VEGF Trap-Eye arms and the laser arm
on the secondary efficacy endpoints will be performed only when the
respective VEGF Trap-Eye arm demonstrates statistically significant
difference from laser arm on the primary endpoint at week 52. To control
the type I error, the secondary endpoints will be tested sequentially in
the order described below:
-CRT assessed by OCT change from baseline to week 52
-Proportion of subjects who gain at least 10 ETDRS letters from baseline
to week 52
-NEI VFQ-25 near activities subscale change from baseline to week 52
-NEI VFQ-25 distance activities subscale change from baseline to week
