Inner Nuclear Layer Thickness, a Biomarker of Metamorphopsia in Epiretinal Membrane, Correlates With Tangential Retinal Displacement

INL thickness is a useful biomarker to evaluate metamorphopsia and appears to be determined by tangential retinal displacement in ERM. Structural changes of the inner retinal layer, which cause Müller cells to be distorted, play a more important role for generation of metamorphopsia than outer retina. Our results provide evidence for the theory that Müller cell functions as an optic fiber in humans.
