Epiretinal pathology of diffuse diabetic macular edema associated with vitreomacular traction.

Purpose: To investigate the ultrastructure of the vitreomacular interface in patients with diffuse diabetic macular edema (DDME) associated with vitreomacular traction.

Design: Laboratory investigation.

Methods: Fifty-five consecutive patients with DDME underwent vitrectomy with en-bloc removal of the inner limiting membrane (ILM) and epimacular tissue.
