Two-year results from the phase 3 YOSEMITE and RHINE trials evaluated faricimab delivered through a personalized treat-and-extend approach in diabetic macular edema (DME). Visual acuity gains were maintained through year two and were noninferior to aflibercept dosed every eight weeks. An important feature was durability: many patients receiving faricimab in the treat-and-extend arms could be extended to 12- or 16-week intervals, reducing the number of injections required over the study period. Anatomic improvements were also sustained, with reductions in central subfield thickness and improved fluid control. For retina specialists, the study reinforces the value of treatment interval personalization. Rather than treating every patient at a fixed frequency, clinicians can adjust dosing according to visual and anatomic response while preserving meaningful gains. This approach may reduce treatment burden for patients who respond well, especially in chronic diseases such as DME where repeated intravitreal injections can become a major barrier to long-term adherence. The study also supports the concept that durability is now a central efficacy endpoint alongside visual acuity and OCT anatomy.

Recent research defines ferro-aging as a conserved iron-lipid axis driving organ decline across primates. Age-related iron dyshomeostasis stimulates ACSL4-mediated lipid peroxidation, promoting cellular senescence. Notably, vitamin C directly inhibits ACSL4, suppressing phospholipid oxidation and multi-organ decay.
