Abstract
Studies have demonstrated the benefit of intravitreous anti–vascular endothelial growth factor (VEGF) injections for improving visual acuity and decreasing retinal thickening in eyes with diabetic macular edema (DME).1-4 Nevertheless, in 32% to 66% of eyes treated with at least 6 monthly injections, edema persisted, often with reduced visual acuity.2 Thus, there is a need for additional treatments for eyes with suboptimal response to anti-VEGF therapy.
