Study objective is to better understand the pathophysiology of diabetic macular edema (DME) by defining the factors that participate in the disease process or may be good biomarkers for disease progression. Study will investigate the temporal relationship between the course of treatment with anti-VEGF therapy and levels of candidate biomarkers previously identified to determine which biomarkers are affected by anti-VEGF therapy with aflibercept. Study will correlate response to therapy to particular biomarkers and attempt to identify those associated with resistance to therapy for DME. Biomarker data will be correlated with serial clinical evaluation of disease progression. 40 subjects with clinically significant DME who plan to undergo anti-VEGF therapy will be treated with intravitreal aflibercept monthly for 6 months. At each visit aqueous humor will be collected and stored (6 samples per patient). At termination of study all specimens will be analyzed for biomarkers identified from previous studies.
