One Year Results of Faricimab for Aflibercept-Resistant Diabetic Macular Edema
Ryan B. Rush
Abstract
Purpose: To assess the 12 month outcomes of intravitreal faricimab (IVF) in treatment-resistant diabetic macular edema (DME) recalcitrant to intravitreal aflibercept (IVA). Methods: This study was undertaken as a retrospective interventional case series of DME subjects receiving care at a single private practice facility. Subjects at baseline had undergone ≥8 IVA injections over the previous 12 months, ≥4 IVA injections over the previous 6 months, had an optical coherence tomography (OCT)-measured central macular thickness (CMT) of ≥320 microns, and had observable edema on OCT. The baseline visit for this study's purpose was considered the examination in which the subject was changed from IVA to IVF. Subjects were managed with a treat-and-extend (TAE) protocol and followed over 12 months from baseline. Results: <0.01). Conclusion: A longer treatment interval and improved functional and anatomical outcomes at 12 months may be attained in a clinically significant minority of aflibercept-resistant DME patients after changing to IVF when a TAE protocol is employed. Specialists may consider IVF whenever resistance to IVA is experienced in this patient population.
