Extracellular spaceInterphotoreceptor matrixSecretedExtracellular matrix


In vertebrates, the photoreceptors are separated from the retinal pigment epithelium by the subretinal space, which contains a specialized extracellular material referred to as interphotoreceptor matrix. The IPM mediates key interactions between the photoreceptors and RPE including adhesion, phagocytosis, outer segment stability, nutrient exchange, development, and vitamin A trafficking in the visual cycle.
