Neuroplasticity01:01

Neuroplasticity

2.6K
Neuroplasticity reflects the brain's remarkable capacity to adapt and evolve, responding dynamically to learning, experiences, or injury by reorganizing its neural circuitry. This reorganization involves creating new neural connections and refining old ones through a series of biological processes that contribute to the brain's lifelong development and adaptability.

Accessory Structures of the Eye

4.3K
Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...

Anatomy of the Eyeball

8.6K
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...

Summary

Amblyopia, or lazy eye, is not purely monocular. New research shows binocular vision capacity and targeted treatments can improve sight in adults with amblyopia.

Area of Science:

  • Neuroscience
  • Ophthalmology
  • Vision Science

Background:

  • Amblyopia was historically viewed as a monocular visual system defect.
  • Emerging evidence indicates that binocular vision capabilities persist in many individuals with amblyopia.
  • This understanding has spurred advancements in quantifying suppression and its impact on visual deficits.

Purpose of the Study:

  • To review recent research on the structure, measurement, and treatment of binocular vision in amblyopia.
  • To explore new therapeutic strategies targeting visual cortex suppressive interactions.
  • To assess the efficacy of these treatments in improving both monocular and binocular function.

Main Methods:

  • Review of recent studies on amblyopia and binocular vision.
  • Analysis of new techniques for quantifying visual suppression.
  • Evaluation of emerging treatments for amblyopia.

Main Results:

  • Binocular vision capacity is present in many amblyopic individuals.
  • New suppression quantification methods offer insights into amblyopia's visual deficits.
  • Emerging treatments show promise in improving visual function, even in adults.

Conclusions:

  • Amblyopia involves complex binocular interactions, not just monocular deficits.
  • Targeted treatments addressing visual cortex suppression are effective.
  • Restoration of binocular function is achievable in amblyopia, including in adults.
