Fig. 4

In degenerative lamellar holes, Müller cells in the foveola are connected to the middle part of lamellar macular hole-associated epiretinal proliferation (LHEP) at the inner surface of the foveal walls. The images show SD-OCT scans through the fovea and parafovea of 6 eyes of 6 patients. The orientations of the scans are shown at the left side. The blue arrowheads indicate LHEP. The yellow arrowheads indicate vitreomacular adhesions. In the smaller images at the right side, the middle part of LHEP is indicated by yellow color, cells of the Müller cell cone are indicated by green color, and the posterior hyaloid is indicated by pink color. Scale bars, 200 µm. ELM, external limiting membrane; ERM: epiretinal membrane; EZ: ellipsoid zone; GCL: ganglion cell layer; HFL: Henle fiber layer; INL: inner nuclear layer; IPL: inner plexiform layer; IZ: interdigitation zone; NFL: nerve fiber layer; ONL: outer nuclear layer; OPL: outer plexiform layer; RPE: retinal pigment epithelium
