Comparison of schistic and degenerative cavitations in tractional and degenerative lamellar holes, respectively. The images show linear SD-OCT scans through the fovea of 18 eyes of 18 patients. a Tractional lamellar holes. b Degenerative lamellar holes. The arrows indicate the levels of the widest lateral extensions of schistic (a) and degenerative cavitations (b). The arrowheads indicate morphological connections between Müller cells in the foveola and lamellar macular hole-associated epiretinal proliferation. 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
