Contrast Sensitivity Changes in Center Involving Diabetic Macular Edema Treated with Aflibercept

To characterize the changes in contrast sensitivity (CS) and retinal anatomy in patients with center involving diabetic macular edema (CDME) measured from baseline to post-loading doses of aflibercept. This single center, prospective, open-label, non-controlled evaluation of five aflibercept intravitreal injections for treatment of CDME over a 16-week period. One eye in each of the forty patients will receive aflibercept every 4 weeks. Subject testing includes measurements of central retinal thickness (CRT), best corrected visual acuity (BCVA), Pelli-Robson (PR) CS, and CamBlobs (CB) CS at 20 weeks post baseline. A total of 40 eyes from 40 patients with CDME were analyzed. The mean age was 62.9 ±10.6 years and 55% were male. At baseline, CRT was 365 ±94.6µm with logMAR BCVA 0.25±0.20. CS PR at baseline was 1.46±0.13 logCS compared to the normal population 1.79±0.10 logCS (P=
