The purpose of this observational study lies in the analysis of a treat-and-extend injection scheme with intravitreal aflibercept (i.e. injection into the eye), as applied in routine practice in previously untreated patients diagnosed with wet age-related macular degeneration.
Data will be collected from the medical files retro- and prospectively. If patients are still under treatment at study initiation and have not yet completed 24 months of treatment with intravitreal aflibercept in a treat-and-extend regimen, data of the remaining observation period will be collected prospectively.

Numbers of injections will be predefined as categories and analyzed in relation to the BCVA changes |
| Baseline and at 12 months; Baseline and at 24 months |
| Mean interval between injections | mean interval displayed in weeks or days | At 12 and 24 months |
| Reasons for the interval length | morphology and / or BCVA /other | At 12 and 24 months |
| Frequency of disease reactivation | Disease activity such as hemorrhage, PED, subretinal fluid, cystoid intraretinal fluid, RPE rip assessed at the investigator's discretion as: none / new or increasing / decreasing / stable | Baseline and at 12 months; Baseline and at 24 months |
| Proportion of eyes gaining or losing ≥ 15 Early Treatment Diabetic Retinopathy Study letters compared to baseline | Proportion evaluated as percentage (%) of eyes | Baseline and at 12 months; Baseline and at 24 months |
| Mean changes from baseline in central retinal thickness (CRT) | micro meter (µm) | Baseline and at 3 months; Baseline and at 12 months; Baseline and 24 months |
