Accessory Structures of the Eye01:17

Accessory Structures of the Eye

4.4K
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

7.5K
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...

Photoreceptors and Visual Pathways01:22

Photoreceptors and Visual Pathways

11.1K
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,...

Acne Infection01:27

Acne Infection

52
Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...

Prosopagnosia01:24

Prosopagnosia

1.1K
Prosopagnosia, also known as face blindness, is the inability to recognize faces. In severe cases, individuals with prosopagnosia may not recognize close family members, including parents and spouses, by their faces. For instance, someone with prosopagnosia might walk past their child in a crowd, only realizing their mistake upon noticing their child's distinctive backpack or favorite jacket. Prosopagnosia specifically impairs facial recognition, while the recognition of other objects or...

Area of Science:

  • Ophthalmology
  • Pediatric Health
  • Public Health

Background:

  • Asthenopia, or visual fatigue, is a common concern in children.
  • Understanding its prevalence and associated factors in schoolchildren is crucial for early intervention.

Purpose of the Study:

  • To determine the prevalence of asthenopia among schoolchildren aged 6-16.
  • To identify potential associated factors and visual function alterations in this population.

Main Methods:

  • A cross-sectional study was conducted with 964 children in Southern Brazil.
  • Data collection involved questionnaires for parents and children, and comprehensive visual function examinations.

Main Results:

  • Asthenopia was prevalent in 24.7% of the studied schoolchildren.
  • Common visual issues included astigmatism (37.8%) and hyperopia (71.6% mild, 13.6% moderate).
  • Abnormalities in near point of convergence (14.0%) and accommodative convergence/accommodation ratio (17.1%) were noted.

Conclusions:

  • Asthenopia affects a considerable proportion of children and adolescents.
  • The prevalence of visual function alterations is comparable to the general population.
  • Further investigation into mechanisms and risk factors is essential, and healthcare providers should monitor visual fatigue for its impact on academic performance.
