Subfoveal scotomas trigger fine-scale fixation reorganization: insights from retinal imaging and retinal-contingent stimulation Open
Fine spatial vision relies on the foveola, the 1-degree retinal region with highest cone density. Despite its importance, the relationship between retinal anatomy, fixational behavior, and visual perception in the foveola is not fully unde…

In Vivo Cone Photoreceptor Topography of the Human Foveola Open
Despite a 1.6-fold range in absolute cone density, foveolar density profiles could be well described by a sigmoidal decay function across all eyes. This established a normative cone density profile of the healthy foveola. It allowed cone d…

Synchronization of visual perception within the human fovea Open
The human brain constructs a model of the world by processing sensory signals with distinct temporal characteristics that may differ in generation and transmission speed within a single sensory modality. To perceive simultaneous events as …

Compression of visual information in redundancy masking follows grouping and segmentation Open
In typical scenes, the available visual information exceeds the processing limits of the visual system.To reduce information, the visual system organizes visual input according to various principles. Forexample, in visual grouping local el…

Invited Session I: Focusing on the Human Fovea: Foveal sampling in space and time Open
Up to very recently, the spatial arrangement of the photoreceptors of the human foveal center and their relationship to vision remained uncharted territory. With adaptive optics photo stimulation techniques that overcome the optical blur o…

Fixational eye movements as active sensation for high visual acuity Open
Perception and action are inherently entangled: our world view is shaped by how we explore our environment through complex and variable self-motion. Even when fixating stable stimuli, our eyes undergo small, involuntary movements. Fixation…

Evaluation of Retinal Sensitivity in Complete Retinal-Pigment-Epithelium and Outer Retinal Atrophy (cRORA) Lesions in Intermediate Age-Related Macular Degeneration (iAMD) by High-Resolution Microperimetry Open
Objective: Lesions characterized as complete retinal pigment epithelium and outer retinal atrophy (cRORA) are linked to the progression of intermediate age-related macular degeneration (iAMD). However, the extent of functional impairment o…

Sub-cone visual resolution by active, adaptive sampling in the human foveola Open
The foveated architecture of the human retina and the eye’s mobility enables prime spatial vision, yet the interplay between photoreceptor cell topography and the constant motion of the eye during fixation remains unexplored. With in vivo …

Neural contrast sensitivity is not affected by myopic blur Open
Purpose The prevalence of myopia is increasing worldwide, accompanied by an increase of potentially under-corrected myopes. Because the neural pathways processing the retinal image are prone to adaptation in relation to the retinal image q…

Assessment of local sensitivity in incomplete retinal pigment epithelium and outer retinal atrophy (iRORA) lesions in intermediate age-related macular degeneration (iAMD) Open
Objective Lesions of incomplete retinal pigment epithelium and outer retinal atrophy (iRORA) are associated with disease progression in intermediate age-related macular degeneration (AMD). However, the corresponding functional impact of th…
