Economic value of anti–vascular endothelial growth factor treatment for patients with wet age-related macular degeneration in the United States. JAMA ophthalmology, 138(1), 40-47. Best outcomes may require clinic visits as frequently as every 1-2 months for monitoring and injections. Onerous visit frequency Physicians attempt to extend the time between patient visits, reducing injection frequency. Current Solution Reduced injection frequency can lead to undertreatment and reduced efficacy. Suboptimal Outcomes "Although multiple anti-VEGF therapies exist, unmet need remains high owing to treatment underutilization…"1 …regular treatment and monitoring requires substantial time commitment and may contribute to poor compliance. This treatment burden has been recognized by ophthalmologists; consequently, personalized treatment strategies attempt to balance the treatment burden against potentially reduced efficacy"1
