Diabetic macular edema: New promising therapies

Figure 3 Spectral-domain optical coherence tomography scans of the macula before (A) and after (B) pars plana vitrectomy in a patient with diabetic macular edema in the left eye. Note the focal vitreomacular adhesion with associated cystoid macular edema and intraretinal hard exudates. Seven months following surgery, the macular edema completely resolved (B), but the Snellen visual acuity was not changed and measured 20/400 likely due to atrophic changes in the outer retina as seen on optical coherence tomography.
