Pathophysiological explanations for metamorphopsia associated with retinal
pathologies generally focus on photoreceptor organization disruption. However,
the retinal microarchitecture is complicated, and we hypothesize that other
retinal cells may also be involved. Metamorphopsia has been widely studied in
eyes with epiretinal membranes and we revisit the idea that Müller cell
displacement causes retinal macropsia. A PubMed query and related article search
for the macula ultrastructure under normal and pathological conditions revealed
an enormous amount of information, particularly ultrahigh definition optical
coherence tomography and other retinal imaging modality studies. Findings of
these imaging studies support our hypothesis that Müller cells, and not cone
photoreceptors, are primarily responsible for macropsia in eyes with epiretinal
membranes. More specifically, we conclude that displacement of Müller cell
endfeet, and not photoreceptor cones, is a more likely the explanation for
retinal macropsia associated with epiretinal membranes.
