Insights

Family history of refractive error and increased near work are significant risk factors for myopia in primary school children. These findings highlight the importance of understanding genetic and environmental influences on childhood vision.

Area of Science:

  • Ophthalmology
  • Pediatric Ophthalmology
  • Public Health

Background:

  • Refractive error is a primary cause of childhood visual impairment.
  • Identifying risk factors is crucial for prevention and management strategies.
  • Childhood refractive errors necessitate targeted public health interventions.

Purpose of the Study:

  • To determine risk factors for refractive errors in primary school children aged 6-12.
  • The study focused on children in Nakhon Pathom province.
  • Investigating the association between refractive error and environmental/genetic factors.

Main Methods:

  • A population-based cross-sectional study was conducted.
  • Data collected on refractive error, parental refractive status, and near work hours.
  • 377 primary school children participated in the assessment.

Main Results:

  • Myopia was the most prevalent refractive error.
  • Children with myopia had a higher likelihood of having myopic parents.
  • Increased hours of near-work activities were associated with myopia.
  • Parental myopia (OR=6.37) and near work (OR=1.019 per diopter-hour/week) were independent risk factors.

Conclusions:

  • Family history of refractive error is a significant predictor.
  • Extended hours of near-work activities are strongly associated with refractive error.
  • These factors independently contribute to the development of refractive errors in children.

Focusing of Light in the Eye01:16

Focusing of Light in the Eye

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

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, whereas...

Diabetic Retinopathy

DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...

Accessory Structures of the Eye

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...
Influence of Earth's Curvature and Atmospheric Refraction on Leveling01:26

Influence of Earth's Curvature and Atmospheric Refraction on Leveling

During leveling, the Earth's curvature and atmospheric refraction introduce deviations in the line of sight from a true horizontal reference. When the line of sight is leveled, it remains perpendicular to the plumb line only at a single point. Beyond this, it deviates due to the Earth’s curvature, represented by the correction C. For a sight distance D, the deviation can be derived using the relationship:This relationship shows that the deviation increases quadratically with distance. Over a...
