This study is a prospective, observational, non-interventional, multicenter, open-label, single arm study in nAMD patients being treated for nAMD with brolucizumab according to the SmPC.
An observational study design, without a strict, mandated visit schedule or mandated treatment regimen was chosen as the most appropriate to collect available data in a real life setting. For that reason, this NIS does not impose a therapy protocol, diagnostic/therapeutic procedure or a visit schedule. The diagnostic or monitoring procedures are only those ordinarily applied to the therapeutic strategy and to routine clinical care and will take place as per investigator's discretion. This includes e.g. visit frequency, injection frequency and types of assessments performed - only data from routine medical practice will be collected as part of the study.

Neovascular Age-related Macular Degeneration (nAMD) | Drug: brolucizumab |
BLUE SKY consists of the two main study modules DEEP BLUE (Observational stuDy to Evaluate fluid resolution and Effectiveness in Patients receiving Beovu (broLUcizumab) in neovascular age-related macular dEgeneration) and BIRL (Brolucizumab In Real Life).
Patients will be enrolled at approximately 32 centers, which will be representatively distributed amongst the 16 German federal states. This will ensure to reflect all state-specific health insurance laws and guidelines. Naïve and pre-treated patients will be included after decision to start treatment with brolucizumab and consent is given. Out of the patients, 1/3 should be pre-treated and 2/3 naïve. All patients will be documented for the DEEP BLUE study module (Full Analysis Set).
For the BIRL module, only naïve patients enrolled in 7 selected centers will be documented. All these centers are equipped with the Zeiss PlexElite OCT-A, needed to assess and analyze BIRL specific objectives in a comparable setting. Only images from routine medical practice will be collected as part of the study.
The study eye will be defined as the first eye treated during the study, the other eye will be considered as fellow eye. If both eyes are treated at baseline, the eye with the worse visual acuity will be chosen as the study eye (if the visual acuity is measured equal, the treating ophthalmologist defines the study eye upon his discretion).
The prospective observation period per patient will be up to 24 months.

- Percentage of patients that are absent of subretinal fluid (SRF) and intra-retinal fluid (IRF) in the study eye. [ Time Frame: month 12 ]This Oucome Measure is part of the Deep Blue module. This primary study objective will be addressed considering treatment naïve and pre-treated patient eyes included in the study, analyzed as two independent groups (naïve and switch).
- Mean change in visual actuity (VA) in the study eye considering treatment naïve subgroup [ Time Frame: Baseline, month 12 ]
Mean change in visual actuity (VA) under clinic specific routine treatment schemes Index date (Baseline): defined as the date of the first anti-VEGF injection (brolucizumab) in patient eyes.
BIRL module
- Morphological CNV-Changes in the study eye considering treatment naïve subgroup [ Time Frame: Baseline, month 12 ]
Morphological Choroidal Neovascularization (CNV)-Changes under clinic specific routine treatment schemes Index date (Baseline): defined as the date of the first anti-VEGF injection (brolucizumab) in patient eyes.
BIRL module
- Fluid resolution after initiation of brolucizumab [ Time Frame: month 24 ]Detailed Outcome Measure will be defined in the Statistical Analysis Plan
- Visual Actuity (VA) change from baseline [ Time Frame: Baseline, month 24 ]Detailed Outcome Measure will be defined in the Statistical Analysis Plan
- Characterize Choroidal Neovascularization (CNV) morphology (BIRL) and activity [ Time Frame: month 24 ]Detailed Outcome Measure will be defined in the Statistical Analysis Plan
- Number of injections and total number of visits [ Time Frame: month 24 ]Detailed Outcome Measure will be defined in the Statistical Analysis Plan
- Describe the distribution of injection intervals [ Time Frame: month 24 ]Detailed Outcome Measure will be defined in the Statistical Analysis Plan
- Number of Spectral Contrast Optical Coherence Tomography (SC-OCTs) done [ Time Frame: month 24 ]Detailed Outcome Measure will be defined in the Statistical Analysis Plan
