Beyond Longer Intervals: Advocating for Regular Treatment of Neovascular AMD.

Personalizing the management of neovascular age-related macular degeneration (nAMD) poses significant challenges for practicing retina specialists and their patients. This commentary addresses some of these complexities, particularly those that arise in the context of an expanding array of intravitreal agents targeting vascular endothelial growth factor (VEGF) and related retinal disease targets. Many of these newer agents approved by the Food and Drug Administration (FDA) for the treatment of nAMD have labeling that indicates that they can provide non-inferior visual outcomes when compared head-to-head with previously available treatments and can be used at significantly extended dosing intervals in some patients. It can be difficult to know if patients should be transitioned to these agents, especially those who are doing well on existing therapies. Although offering extended intervals may be appropriate for some patients with excellent disease control, retina specialists know that undertreatment risks the loss of visual acuity (VA). It can also be challenging for clinicians to interpret the results delivered by clinical trial treatment protocols compared with what is likely to occur in real-world office settings. Many retina specialists use less liberal treatment paradigms than employed in clinical study protocols and consequently many patients experience shorter injection intervals. Since VA is most closely linked to quality of life, it should be prioritized compared with other endpoints. The authors advocate for maintaining consistent treatment schedules dictated by disease control instead of switching therapies even in the presence of small amounts of macular fluid that may occur with longer injection intervals.
