Fig. 1: Representative examples of morphological phenotypes of epiretinal membrane foveoschisis (ERM-F), lamellar macular hole (LMH) and mixed ERM-F/LMH graded in this study.

A Normal foveal contour. B Open-flat ERM-F. C Open-elevated ERM-F, with foveal edges elevated above the surrounding retinal plane (white arrowheads). D Closed ERM-F with epiretinal membrane covering the fovea (white arrowhead). E Mixed ERM-F/LMH showing schisis, undermined edge (dashed arrow), and irregular foveal contour. F LMH with undermined edges and retinal tissue loss (dashed arrows), irregular foveal contour, epiretinal proliferation (star), foveal bump (white arrow), and ellipsoid zone disruption (black arrowheads).
