Abstract

Metamorphopsia is a common symptom of macular disease and can persist after macular surgery. Disarrangement of the photoreceptors is a plausible theory for metamorphopsia. Removal of the internal limiting membrane (ILM) causes the contraction of exposed retinal nerve fibers (RNFs), and consequently the macula is deformed. After removal of the ILM to a large extent, the fovea is displaced to the optic disc following the summed vector force of RNF contraction. The photoreceptors may be displaced concurrently with deformation of the inner layers of the macula, resulting in metamorphopsia. This article reviewed published papers related to the mechanism of metamorphosia and interpreted the results based on the above concepts.
