Visual System01:26

Visual System

Light enters the eye through the cornea, a transparent, dome-shaped surface covering the surface of the eyeball that helps to direct and focus incoming light. This light is then channeled toward the pupil, an adjustable opening whose size is controlled by the iris. The iris, a pigmented muscle, regulates the amount of light entering the eye by contracting or dilating the pupil, thereby ensuring optimal light levels for clear vision.
Once through the pupil, the light passes through the lens, a...
Vision01:24

Vision

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.
Depth Perception and Spatial Vision01:15

Depth Perception and Spatial Vision

Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.

Area of Science:

  • Ophthalmology
  • Neuroscience
  • Biomedical Engineering

Background:

  • Degenerative retinal diseases cause photoreceptor loss, leading to blindness.
  • Current treatments include gene therapy, cell transplantation, and drug therapies.
  • Inner retinal rewiring and neuronal degeneration complicate treatment in conditions like retinitis pigmentosa.

Purpose of the Study:

  • To introduce neural prosthetics as a complementary treatment for degenerative retinal diseases.
  • To explore the potential of artificial vision technologies in restoring sight.
  • To highlight recent advancements in artificial vision and their integration with other therapies.

Main Methods:

  • Electrical stimulation of retinal ganglion cells.
  • Development of the bionic retina.
  • Molecular engineering and nanotechnology to induce photosensitivity in non-light-sensitive cells.
  • Targeting ion channels to specific cell types and regions.
  • Sophisticated image processing algorithms based on retinal signal processing.

Main Results:

  • Demonstration that electrical stimulation of retinal ganglion cells can create visually useful percepts.
  • Advancements in rendering cells light-sensitive and targeting ion channels.
  • Development of sophisticated image processing for artificial vision.

Conclusions:

  • Neural prosthetics represent a significant advancement in treating blindness caused by degenerative retinal diseases.
  • Artificial vision technologies, combined with gene, pathway, and cell-based therapies, offer a powerful new armamentarium for ophthalmologists.
  • These technologies augment, rather than replace, existing treatment options.
