Directionality and alignment of the foveal receptors, assessed with light scattered from the human fundusin vivo
TLDR
In this paper, the directionality of the foveal receptors of four subjects was assessed with a technique based on lightscattering and a psychophysical technique, and the width and orientation of the absorbance diagram (difference between the scattering diagram in a bleached and unbleached state of the visual pigment) were compared with the Stiles-Crawford function.About:

Parametric representation of Stiles–Crawford functions: normal variation of peak location and directionality
TL;DR: Large-sample norms for foveal SCE peak location and spread are reported, various mathematical forms used for the empirical description of SCE data sets are discussed, and these norms are compared with values determined in other laboratories.

Optical fiber properties of individual human cones.
Austin Roorda,David R. Williams +1 more
TL;DR: Direct imaging with the Rochester adaptive optics ophthalmoscope used to directly image the tuning properties of individual cones in living human eyes found that cone disarray is very small, accounting for less than 1% of the breadth of the tuning function of an ensemble of cones.
Journal ArticleDOI
Modulation transfer of the human eye as a function of retinal eccentricity
TL;DR: In this paper, the authors measured the monochromatic image quality of the eye across a wide visual field (120°), with natural pupil (4 mm) and accommodation (3 diopters).
Journal ArticleDOI
Birefringence of the human foveal area assessed in vivo with Mueller-matrix ellipsometry
TL;DR: In this paper, Mueller matrix ellipsometry was used to assess retinal birefringence in the foveal and parafoveal regions of the human eye.
Journal ArticleDOI
Images of cone photoreceptors in the living human eye
TL;DR: A high-resolution fundus camera is constructed and cones with a spacing as small as 3.5 microns are resolved in single images of the fundus, showing the superiority of the eye's optics over the spatial sampling limits of the retina when the eyes' optical quality is optimized.

Lateral diffusion of rhodopsin in the photoreceptor membrane
Mu-ming Poo,Richard A. Cone +1 more
TL;DR: Rhodopsin undergoes rapid lateral diffusion in the disk membranes of isolated frog and mudpuppy rods, which indicates the disk membrane is highly fluid with a viscosity of ∼1P.

Signal Transmission along Retinal Rods and the Origin of the Electroretinographic a -Wave
R. D. Penn,W. A. Hagins +1 more
TL;DR: The spatial distribution of membrane current of the rods of the rat retina is studied by an improved method using arrays of extracellular microelectrodes inserted in the receptor layer under direct vision by infrared microscopy.

Lateral Diffusion of Visual Pigment in Photoreceptor Disk Membranes
Paul A. Liebman,G. Entine +1 more
TL;DR: Visual pigment molecules are found to move transversely, but not longitudinally, in both rod and cone outer segments of mud puppy and frog, consistent with the idea that they are immersed in a two-dimensional fluid disk membrane.

The Stiles-Crawford effect--explanation and consequences.
Allan W. Snyder,Colin Pask +1 more
TL;DR: The physical properties of an isolated human foveal cone completely determine the Stiles-Crawford effect of the first kind (SC—1) both in the sensitivity to angle of incidence and in the great variation of that sensitivity to wavelength.

Vision and Resolution in the Central Retina
TL;DR: The structure of the retina is consistent, numerically, with resolution acuity at high illumination but does not account for observed changes in acuity as retinal illumination is reduced.
