The scientific community knows that vascular endothelial growth factor (VEGF) causes increased, vascular permeability, resulting in diabetic macular edema (DME) in the ischemic retina, but how to stop the VEGF drive remains the challenge.
The Diabetic Retinopathy Clinical Research Network’s (DRCR.net) Protocol T—the first head-to-head-to-head comparison among aflibercept (Eylea, Renegeron Pharmaceuticals), ranibizumab (Lucentis, Genentech), and bevacizumab (Avastin, Genentech)—found in its first-year results that all three agents improved vision and reduced edema effectively.
Sustained intraocular delivery of fluocinolone acetonide (FAc) using the FAc 0.19 mg intravitreal implant (Iluvien, Alimera Sciences) improves and slows progression of diabetic retinopathy (DR), according to findings of post-hoc analyses of data from the pivotal Fluocinolone Acetonide for Diabetic Macular Edema (FAME) trials.
Treating diabetic macular edema (DME) has evolved from the ETDRS-style focal/grid laser being the standard of care since 1985 to the modern era of pharmacotherapy—with anti-vascular endothelial growth factor (VEGF) injections now taking center stage as primary treatment for most patients.
Volume-rendered optical coherence tomography (OCT) imaging allows new insight into retinal vascular flow and morphological changes in eyes with macular edema (ME), and the information obtained is the basis for new ideas about the pathogenesis of ME and therapeutic intervention, according to Richard F. Spaide, MD, Vitreous Retina Macula Consultants of New York.
Results from the phase II TANZANITE clinical trial support further investigation of adding suprachoroidal triamcinolone acetonide to anti-vascular endothelial growth factor therapy for treatment-naïve retinal vein occlusion.
Researchers have identified a new biomarker they believe can be used as a predictor of vision change in patients with diabetic macular edema, either during the natural history of the disease or after undergoing anti-VEGF therapy. The biomarker is disorganization of the retinal inner layers, or DRIL.
When it comes to finding new treatments for diabetic macular edema (DME), there is no shortage of promising targets, said Peter A. Campochiaro, MD. He presented an overview of future compounds with various mechanisms of action that may change how clinicians treat DME.
