The Retina01:32

The Retina

69.1K
The retina is a layer of nervous tissue at the back of the eye that transduces light into neural signals. This process, called phototransduction, is carried out by rod and cone photoreceptor cells in the back of the retina.

Anatomy of the Eyeball

7.1K
The eye is a spherical, hollow structure composed of three tissue layers. The outer layer — the fibrous tunic, comprises the sclera — a white structure — and the cornea, which is transparent. The sclera encompasses some of the ocular surface, most of which is not visible. However, the 'white of the eye' is distinctively visible in humans compared to other species. The cornea, a clear covering at the front of the eye, enables light penetration. The eye's middle...

Vision01:24

Vision

53.5K
Vision is the result of light being detected and transduced into neural signals by the retina of the eye. This information is then further analyzed and interpreted by the brain. First, light enters the front of the eye and is focused by the cornea and lens onto the retina—a thin sheet of neural tissue lining the back of the eye. Because of refraction through the convex lens of the eye, images are projected onto the retina upside-down and reversed.

Photoreceptors and Visual Pathways01:22

Photoreceptors and Visual Pathways

6.0K
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category,...

Area of Science:

  • Neuroscience
  • Ophthalmology

Background:

  • Amacrine cells (ACs) are diverse retinal neurons with varied functions, including neuropeptide secretion and inhibitory connections.
  • Vasoactive intestinal peptide (VIP)-expressing amacrine cells (VIP-ACs) are GABAergic neurons that interact with bipolar cells (BCs), other ACs, and retinal ganglion cells (RGCs).

Approach:

  • This review systematically examines the structure, distribution, and function of retinal VIP-ACs across different species.
  • It synthesizes current knowledge to provide a comprehensive understanding of these cells.

Key Points:

  • VIP-ACs exhibit distinct morphology and distribution patterns that vary between species.
  • These cells play significant roles in myopia, light responses, and retinal vascular diseases.
  • Their neuropeptide secretion and inhibitory connections are key to their function.

Conclusions:

  • Retinal VIP-ACs exhibit early development.
  • Despite interspecies variations in morphology and distribution, VIP-ACs share conserved functions in ocular disease contexts.
  • Understanding VIP-ACs is increasingly important for refractive development and disease research.
