Clinical Study

Determination of a New Parameter, Elevated Epiretinal Membrane, by En Face OCT as a Prognostic Factor for Pars Plana Vitrectomy and Safer Epiretinal Membrane Peeling

Figure 1

Diffuse infiltrating epiretinal membrane (EM) with a small elevated area. (a) Macular thickness map obtained with spectral domain-optical coherence tomography (SD-OCT). (b) Line scanning ophthalmoscope (LSO) SD-OCT image. (c) Automatic identification of the EM surface (upper white line) and selection of the retinal surface (lower white line). (d) Black pixelated areas calculated automatically reveal elevated EM areas, overlaid with the LSO image in transparency.
