WebHere we use parafoveal stimuli to measure center-surround perception of contrast in older and younger adults. We measure the influence of both near and far surround because … Parafovea or the parafoveal belt is a region in the retina that circumscribes the fovea and is part of the macula lutea. It is circumscribed by the perifovea. See more In reading, information within 1° (approximately 6–8 characters) of the point of fixation is processed in foveal vision, while information up to 6° of visual angle benefits from parafoveal preview. Studies have shown … See more Information in the parafovea can influence the processing of a scene. In categorization tasks of natural scenes information from the parafovea can be used to determine … See more • Eye movement in reading • Eye movement in music reading • Fixation (visual) • Optical coherence tomography (OCT) See more • Schematic diagram of the macula lutea of the retina, showing perifovea, parafovea, fovea, and clinical macula • Time-Domain OCT of the macular area of a retina at 800 nm, axial resolution 3 µm • Spectral-Domain OCT macula cross-section scan.
