Abstract

Purpose:To summarize the findings of long-term outcomes of anti-vascular endothelial growth factor (VEGF) therapy (≥36 months) in patients with exudative age-related macular degeneration.Methods:Studies reporting long-term outcomes (≥36 months) of anti-VEGF therapy (n = 11) were identified and analyzed for changes in visual acuity (VA), optical coherence tomography, and safety findings.Results:Six prospective extension studies of Phase 3 clinical trials and five retrospective evaluation studies were identified. The largest improvements in VA with anti-VEGF treatment were found in Years 1 to 2 after treatment initiation. In five studies, VA ultimately declined below patients' pretreatment initial baseline; in three studies, VA ultimately returned to patients' baseline; in three studies, VA decreased but ultimately remained improved over patients' baseline. There was a trend demonstrating that a higher frequency of intravitreous injections showed a better maintenance in VA. Rates of adverse events were similar to previous registration studies of anti-VEGF drugs.Conclusion:The body of evidence to date regarding long-term anti-VEGF treatment indicates a variable course at greater than 36 months follow-up and seems to be dependent on the treatment protocol. Consistent dosing with fluid-free interval is suggested to maintain VA gains in patients with exudative age-related macular degeneration. There is no evidence suggesting that there are additional adverse events from long-term anti-VEGF use.
