Port Delivery Systems Reduce Injection Burden for Retina Disease
Refillable port delivery systems, surgically implanted devices that continuously release anti-VEGF therapy over six-month intervals, are converting wet age-related macular degeneration treatment from a monthly injection regimen into a twice-yearly office procedure, meaningfully reducing both patient burden and specialist chair time per treated eye. This is pushing retina specialists to requalify treatment protocols for appropriate patients well ahead of typical practice guideline cycles, since injection fatigue remains a leading cause of treatment discontinuation in real-world care. Manufacturers with validated refill safety and durability data are capturing disproportionate share of this conversion wave as evidence accumulates across major retina practices.
