Optimizing Visual Outcomes in Patients With Neovascular Age-Related Macular Degeneration: the Potential Value of Sustained Anti-VEGF Therapy.

ABSTRACT

Neovascular age-related macular degeneration (nAMD) leads to irreversible central vision loss if untreated. Frequent administration of anti-vascular endothelial growth factor (anti-VEGF) injections inhibits disease activity with excellent functional and morphological benefits. However, these injections pose a heavy therapeutic burden, and treatment discontinuation is common. Although current anti-VEGF treatment paradigms, such as treat-and-extend, mitigate treatment burden while still leading to acceptable vision outcomes, they fail to sustain initial vision gains for many. Novel longer-acting anti-VEGF therapies may reduce the overall burden on nAMD patients. Gene therapy might offer a paradigm shift by providing continuous expression of anti-VEGF, potentially decreasing treatment requirements and improving long-term vision outcomes.
