Insights

Undercorrecting myopia in 12-year-old Chinese children did not affect myopia progression or axial elongation over one year. However, greater undercorrection was associated with decreased myopia progression and accommodative lag.

Area of Science:

  • Ophthalmology
  • Pediatric Ophthalmology
  • Myopia Research

Background:

  • Myopia is a growing public health concern in children.
  • Understanding factors influencing myopia progression is crucial for effective management.
  • The impact of undercorrection on myopia progression requires further investigation.

Purpose of the Study:

  • To prospectively evaluate the effects of myopia undercorrection on myopia progression and axial elongation.
  • To investigate these effects in a cohort of 12-year-old Chinese children.

Main Methods:

  • A prospective observational study involving 1,769 children followed for 1 year.
  • Ocular examinations included cycloplegic autorefraction, axial length, and accommodative lag.
  • Myopia undercorrection was defined as a visual acuity improvement of at least 2 lines with subjective refraction.

Main Results:

  • Of 253 myopic children, 47.4% were undercorrected and 52.6% were fully corrected.
  • No significant differences in myopia progression or axial elongation were observed between undercorrected and fully corrected groups at 1 year.
  • Myopia progression significantly decreased with increasing undercorrection (P=0.02), and accommodative lag decreased with increasing undercorrection (P<0.01).

Conclusions:

  • One-year spectacle correction for myopia in Chinese children did not result in different myopia progression or axial elongation between undercorrected and fully corrected groups.
  • While no difference in overall progression was found, a trend suggests potential benefits of undercorrection on myopia progression and accommodative lag.

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...

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...

Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
Drugs such as carbonic anhydrase inhibitors, α2- and...

Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

Distance Corrections01:15

Distance Corrections

To achieve precise distance measurements, especially in surveying and construction, certain corrections must be applied to account for potential sources of error like the standardization errors, temperature variations, and slope adjustments.Standardization error emerges when measurement equipment undergoes changes, such as wear, repairs, or weather impacts. To address this, surveyors compare the equipment’s readings to a standard. This process identifies any deviation that might lead to...
