Outer Plexiform Layer Angle: A Prognostic Factor for Idiopathic Macular Pucker Surgery

Figure 2

The OPL angle is measured from two lines (red) drawn from the OPL at the fovea (illustrated by yellow dots) to the furthermost intersecting point at either side of the OPL (illustrated by blue dots). (a) Patients’ retinas with greater prepeeling OPL angle (≥130°). (b) Patients’ retinas that had smaller prepeeling OPL angle (<130°). (c) Pre-ERM/ILM peeling OCT images (with the OPL angle of 174° as an example at the top left OCT image). (d) Post-ERM/ILM peeling OCT images. Abbreviations: OPL, outer plexiform layer; OCT, optical coherent tomography; ERM, epiretinal membrane; ILM, internal limiting membrane.
