Structure and function of the bird fovea

This review gives an overview of the cellular composition of the bird fovea, with special regard to Müller glial cells that provide the mechanical stability of the foveal tissue.

Foveal shape, ultrastructure and photoreceptor composition in yellow-legged gull, Larus michahellis (Naumann, 1840)

The anatomical and histological features of the foveae in a gull, Larus michahellis, were investigated combining immunofluorescence and transmission electron microscopy, and a central convexiclivate deep fovea was observed near of the pecten oculi.

In vivo chromatic and spatial tuning of foveolar retinal ganglion cells in Macaca fascicularis

The majority of the L vs. M cone opponent cells serving the most central foveolar cones have spatial transfer functions that peak at high spatial frequencies, reflecting strong surround inhibition that sacrifices sensitivity at low frequencies but preserves the transmission of fine detail in the retinal image.

Immunohistological Study of Monkey Foveal Retina

Groups of undifferentiated retinal-stem-cell-like cells in the foveola might be involved in maintaining morphology and regeneration, and that neurogenesis may occur.

Human Foveal Cone and RPE Cell Topographies and Their Correspondence With Foveal Shape

There is a strong relationship between cone and RPE cell spacing and the shape of the human adolescent and adult fovea, adding to the existing evidence of the critical role that the RPE serves in fetal foveal development and through adolescence.

Normal and abnormal foveal development

The outer segment thickness is a surrogate marker for cone density and in foveal hypoplasia this correlates strongly with visual acuity, and in preverbal children grading FH can help predict futureVisual acuity.

Two different populations of Müller cells stabilize the structure of the fovea: an optical coherence tomography study

The Müller cell cone provides the foveal stability in cases of a cystic disruption of the fveola and the sealing of outer macular defects by Müller cells is documented.

Increased neuron density in the midbrain of foveate birds results from profound change in tissue morphogenesis

It is found that neuron densities in the largest visual center of the midbrain – i.e., the optic tectum – are two to four times higher in modern birds with one or two foveae compared to birds deprived of this specialty.

Composition of the Inner Nuclear Layer in Human Retina

Despite large changes in the absolute density of INL cell populations across the retina, their proportions remain relatively constant and may have relevance for interpreting diagnostic signals such as the electroretinogram and optical coherence tomogram.

Glia of the human retina

The human retina contains three types of glial cells: microglia and two types of macroglia, astrocytes and Müller cells. Macroglia provide homeostatic and metabolic support to photoreceptors and



The deep fovea as a focus indicator

It is shown how the deep convexiclivate fovea can act as a sensitive, directional focus indicator over a small area of image.

Canine Retina Has a Primate Fovea-Like Bouquet of Cone Photoreceptors Which Is Affected by Inherited Macular Degenerations

The results challenge the dogma that within the phylogenetic tree of mammals, haplorhine primates with a fovea are the sole lineage in which the retina has a central bouquet of cones and suggest a predilection for naturally-occurring retinal degenerations to alter this cone-enriched area fills the void for a clinically-relevant animal model of human macular degenerations.

Quantitative morphology of the central fovea in the primate retina.

The comparison with the peripheral primate retina suggests that the densities of horizontal and bipolar cells, but not of amacrine and Müller cells, are correlated with the density of cone cell pedicles.

Müller cell alignment in bird fovea: possible role in vision.

This work describes how the endfeet of Müller cells line the walls of the foveal pit in the Pied Flycatcher, and how the Müller cell body extends its processes towards individual cones, forming machinery that could allow for light transfer from the pit wall to the photoreceptor layer alongside the pit.

The ultrastructure of monkey foveal photoreceptors, with special reference to the structure, shape, size, and spacing of the foveal cones.

A systematic electron microscopic study was made of the structure of foveal cones of Macaca spp. Transverse sections of inner (IS) and outer segments (OS) were made in sequence, from the pigment
