Completed
Conditions
Neovascular Age-Related Macular Degeneration
Registration Number
NCT06699914
Lead Sponsor
Novartis Pharmaceuticals
Brief Summary

A retrospective, observational, single-arm, non-randomized cohort study of ocular treatment in nAMD patients in Japan who had records of at least 12 months of follow-up after their first brolucizumab intravitreal injection. Patients who had records of at least 12 months of visits after the first brolucizumab injection (index date) were identified during the index period and were recruited during the data collection/recruitment period.

Demographic: Number of Patients per Age CategoryBaseline

Age categories:

* Less than 80 years old.

* 80 years or older.

Number of Patients per Clinical CharacteristicBaseline

Clinical characteristics included:

* Bilateral age-related macular degeneration (AMD)

* Subtype of AMD, choroidal neovascularization (CNV)

Clinical Characteristic: Time Between Diagnosis and First Brolucizumab InjectionBaseline
Clinical Characteristic: Time Between Diagnosis and First TreatmentBaseline
Clinical Characteristic: Central Subfield Thickness (CSFT)Baseline
Clinical Characteristic: Visual Acuity (VA)Baseline

Visual Acuity (VA) was measured with Early Treatment Diabetic Retinopathy Study (ETDRS) letters.

Conversion of VA readings to approximate ETDRS Letters:

* For Snellen fraction decimal \>0.025 (\<logMAR1.60) the following formula was used:

• approximate ETDRS Letters = 85+50\*log10 (Snellen fraction)

* For Snellen fractions decimal ≤0.025 four bins were defined:

* \>0.020 to 0.025 (logMAR 1.70 to 1.60) was 5 letters

* \>0.015 to 0.020 (logMAR 1.82 to 1.70) was 3 letters

* \>0.005 to 0.015 (logMAR 2.30 to 1.82) was 1 letter

* ≤0.005 (logMAR ≥2.30) is 0 letter
