Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

834
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

Muscles of the Eye01:20

Muscles of the Eye

4.0K
The muscles of the eye are sophisticated structures that control eye movement and focus, allowing for the precise and rapid adjustments necessary for vision. The human eye is controlled by ten muscles — six extraocular muscles, three intraocular muscles, and one primary eyelid retractor muscle.
Extraocular Muscles
The six extraocular muscles surround the eyeball and control its movements. They are responsible for a wide range of eye motions, including looking up, down, left, right, and...

Accessory Structures of the Eye

3.4K
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...

Focusing of Light in the Eye01:16

Focusing of Light in the Eye

5.5K
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...

In- and Out-Groups

42.9K
People all belong to a gender, race, age, and social economic group. These groups provide a powerful source of our identity and self-esteem (Tajfel & Turner, 1979) and serve as our in-groups. An in-group is a group that we identify with or see ourselves as belonging to.

Vision01:24

Vision

59.5K
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.

Summary
This summary is machine-generated.

Amblyopia, or lazy eye, affects more than just the reduced-vision eye. Research shows deficits in the fellow eye impact overall visual and motor skills in children with amblyopia.

Area of Science:

  • Neuroscience
  • Ophthalmology
  • Developmental Pediatrics

Background:

  • Amblyopia is a neurodevelopmental visual disorder from early discordant visual experience.
  • Traditionally, the non-amblyopic fellow eye is considered normal and sufficient for visual tasks.
  • This assumption is challenged by evidence of deficits in the fellow eye.

Purpose of the Study:

  • To review current research on ocular motor and visual deficits in the fellow eye of amblyopic individuals.
  • To examine the impact of these deficits on visuomotor and visuocognitive skills.
  • To highlight the need for comprehensive rehabilitation strategies.

Main Methods:

  • Review of recent scientific literature on amblyopia and fellow eye function.
  • Analysis of studies investigating ocular motor, visual, and visuomotor performance.
  • Synthesis of findings related to amblyopic children's skills.

Main Results:

  • Evidence indicates ocular motor and visual deficits exist in the fellow eye during monocular and binocular viewing.
  • These deficits affect visuomotor and visuocognitive abilities in amblyopic children.
  • The assumption of a fully functional fellow eye is not supported by current research.

Conclusions:

  • Amblyopia impacts both eyes, not just the amblyopic one.
  • Deficits in the fellow eye require consideration in prevention and rehabilitation strategies.
  • Future research should focus on holistic treatment approaches for amblyopia.
