Objective Assessment of Photoreceptor Displacement and Metamorphopsia

Abstract

PHOTORECEPTOR displacement in the absence of retinal detachment is an essential feature of retinal diseases accompanied by metamorphopsia, such as macular holes and macular pucker. These conditions can be bothersome despite excellent monocular visual acuity in both eyes, because binocular fusion is compromised by incongruent central image portions that compete for dominance (binocular rivalry).
