nAMD

This is a multicenter, randomized, double-blind study designed to compare the efficacy and safety of the investigational drug GNR-139 with the reference drug Eylea in treatment-naive patients with neovascular age-related macular degeneration (nAMD). Participants will be randomly assigned to receive either GNR-139 or Eylea. Neither the participants nor the study doctors will know which treatment is being administered. Both drugs will be given as an intravitreal injection dose of 8 mg (0.07 mL at a concentration of 114.3 mg/mL). Patients meeting the eligibility criteria will be randomised in a 2:1 ratio into one of two treatment groups: * Group I (GNR-139): 120 patients; * Group II (Eylea®): 60 patients. The main goal of the study is to evaluate if GNR-139 has similar efficacy to Eylea. This will be determined by measuring the change in the Best-Corrected Visual Acuity (BCVA) score at Week 8 in participants who completed the treatment.

The aim of this trial is to demonstrate similarity in efficacy between ABP 938 8 mg and aflibercept (US) 8 mg by evaluating the change in best corrected visual acuity (BCVA) in participants with neovascular age-related macular degeneration (nAMD)

The goal of this multicentre observational study is to evaluate the interval-extension potential, effectiveness, and safety of intravitreal aflibercept 8 mg in pretreated eyes with neovascular age-related macular degeneration (nAMD) or diabetic macular oedema (DME) under routine clinical practice in Portugal. It consists in an ambidirectional longitudinal cohort with retrospective collection of pre-switch clinical and treatment history and prospective follow-up after initiation of intravitreal aflibercept 8 mg in routine clinical practice. The main questions it aims to answer are: \- Can treatment intervals be extended after switching to intravitreal aflibercept 8 mg while maintaining disease control in pretreated eyes with nAMD or DME? What are the functional, anatomical, and safety outcomes associated with intravitreal aflibercept 8 mg in routine clinical practice? Participants are adults with nAMD or DME who have previously received intravitreal treatment and are switched to aflibercept 8 mg as part of routine clinical care. No study-specific interventions or procedures are performed. Clinical data are collected prospectively through the Portuguese national Retina.PT registry during routine follow-up visits, including treatment patterns, injection intervals, visual acuity, retinal anatomical assessments, and ocular and systemic safety outcomes.
