The study was terminated earlier since the obtained sample was not representative of the Portuguese population, and pointed to the high fragility in evaluating the data, making it difficult to carry out a statistical study and draw valid conclusions.

This study is a prospective, observational, non-interventional, multicenter, open-label, single arm study in patients being treated for nAMD with brolucizumab in Portugal.

Naïve and pre-treated patients will be included after decision to start treatment with brolucizumab and consent is given.

The baseline visit will be used to assess eligibility and collect baseline characteristics information. 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 follow-up visits will take place at a frequency defined as per investigator's discretion. Patients that have not received an intravitreal anti-VEGF injection or visited an eye specialist for at least 6 months will be discontinued from the observation.

Retrospective data will be collected for switch patients starting treatment with brolucizumab for up to six months before baseline. Patients, already being treated with brolucizumab may also be included. Here, retrospective data will be collected since the first brolucizumab injection.

Inclusion Criteria:

1. Diagnosis of nAMD
2. Male and Female patients with ≥40 years of age at index
3. Receipt of at least one injection of brolucizumab during the recruitment period
4. Signed written informed consent

Exclusion Criteria:

1. Patients treated for RVO, DME, mCNV, and have diagnoses of diabetes-related macular degeneration within 6 months prior to the index date
2. Receipt of any anti-VEGF treatment other than brolucizumab in the study eye at index date
3. Central subfield of the study eye affected by fibrosis or geographic atrophy or total area of fibrosis >50% of the total lesion in the study eye at Screening
4. Any active intraocular or periocular infection or active intraocular inflammation in either eye at index date
5. Patients who have been on anti-VEGF treatment for longer than 3 years (before index date)
6. Patients that have any contraindication and are not eligible for treatment with brolucizumab as according to the SmPC
7. Any medical or psychological condition in the treating physician's opinion which may prevent the patient from the 24 months study participation
8. Patients participating in parallel in an interventional clinical trial
9. Patients participating in parallel in any other NIS generating primary data for an anti-VEGF drug
10. Retinal pigment epithelial rip/tear in the study eye at Screening or Baseline or current vitreous hemorrhage or history of vitreous hemorrhage in the study eye within 4 weeks prior to Baseline
11. Subretinal blood affecting the foveal center point and/or >50% of the lesion of the study eye at Screening

This study will include an estimated number of 120 naïve patients and 180 switch patients with a diagnosis of nAMD being treated with brolucizumab in private clinics in Portugal during the recruitment period
