7 de fev. de 2020 · Abstract. We summarize the development, structure, different neural types and neural circuitry in the human fovea. The foveal pit is devoid of rod photoreceptors and of secondary and tertiary neurons, allowing light to directly stimulate cones and give us maximal visual acuity.
1 de set. de 2022 · Early development of the fovea has been documented by histological studies over the past few decades. However, structural distortion due to sample processing and the paucity of high-quality post-mortem tissue has limited the effectiveness of this approach.
10 de abr. de 2024 · The fundamental cellular plan of the fovea is similar to that of the peripheral retina ().In both cases, cells comprise six main classes, most of which can be divided into multiple types: photoreceptors (PRs), which sense light; interneurons (horizontal, bipolar, and amacrine cells), which process visual information relayed from PRs; retinal ganglion cells (RGCs), which integrate input from ...
4 de mai. de 2020 · The histopathology study was approved by the Institutional Review Board at the University of Alabama at Birmingham. In vivo multimodal imaging analysis An 84-year-old white man diagnosed with nAMD in his right eye and non-neovascular AMD in his left eye underwent comprehensive ophthalmologic examination and multimodal imaging.

Foveal specializations include a very high density of cone photoreceptors with displacement of inner retina neurons, as well as their vascular support, hundreds of microns away from the foveal center. The most central cones are located in the foveola, a 350 μm rod-free region comprising the floor of the foveal depression [1].

Histologic features of a normal fovea comprise a central area exclusively containing cones with elongated outer segments (OS) underlying a capillary-free zone and surrounded by separation of inner retinal layers. 1 The advent of optical coherence tomography (OCT), which allows noninvasive, cross-sectional imaging of the retina, made possible the...
