A Standardized Obstacle Course for Assessment of Visual Function in Ultra Low Vision and Artificial Vision

13.5K
We describe an indoor, portable, standardized course that can be used to evaluate obstacle avoidance in persons who have ultralow vision. The course is relatively inexpensive, simple to administer, and has been shown to be reliable and...

Vision

59.4K
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.

This video article illustrates the set-up, the procedures to patch cell bodies and how to implement dynamic clamp recordings from ganglion cells in whole-mount mouse retinae. This technique allows the investigation of the precise contribution of excitatory and inhibitory synaptic inputs, and their relative magnitude and timing to neuronal...

Characterization of the Sense of Agency over the Actions of Neural-machine Interface-operated Prostheses

8.3K
Here we present a protocol which characterizes the sense of agency developed over the control of sensate virtual or robotic prosthetic hands. Psychophysical questionnaires are employed to capture the explicit experience of agency, and time interval estimates (intentional binding) are employed to implicitly measure the sense of...

Color Vision01:24

Color Vision

1.4K
Color perception begins in the retina, the light-sensitive layer at the back of the eye. Two main theories explain how colors are seen: the trichromatic theory and the opponent-process theory. The trichromatic theory, proposed by Thomas Young in 1802 and extended by Hermann von Helmholtz in 1852, suggests that color vision is based on three types of cone receptors in the retina. These cones are sensitive to different but overlapping ranges of wavelengths corresponding to red, blue, and green.

Area of Science:

  • Ophthalmology
  • Neuroscience
  • Biomedical Engineering

Background:

  • Outer retinal degenerative diseases like retinitis pigmentosa and geographic atrophy preserve the inner retinal ganglion cell layer.
  • Current treatments for these conditions are limited, leading to significant vision loss.

Purpose of the Study:

  • To review the principles and applications of retinal prostheses for restoring vision.
  • To discuss the role of rehabilitation in adapting to artificial vision.

Main Methods:

  • Subretinal and epiretinal prostheses utilize microphotodiode or microelectrode arrays to electrically stimulate retinal ganglion cells.
  • Patients undergo specialized rehabilitation to interpret phosphene patterns generated by the implants.

Main Results:

  • Electrical stimulation of the intact ganglion cell layer can create visual percepts (phosphenes).
  • Successful interpretation of phosphenes through rehabilitation enhances orientation, mobility, and overall quality of life.
  • Alternative strategies targeting the lateral geniculate nucleus or visual cortex are under investigation for advanced retinal and optic nerve degeneration.

Conclusions:

  • Retinal prostheses offer a promising approach to vision restoration in specific degenerative retinal diseases.
  • The combination of implanted devices and targeted rehabilitation is crucial for functional visual recovery.
  • Future research aims to expand the applicability of visual prostheses to a broader range of vision-impairing conditions.
