Summary
Preschool myopia often progresses, but some children show stable vision. Key factors like age, sex, and initial prescription influence the rate of myopia progression in young children.
Area of Science:
- Ophthalmology
- Pediatric Ophthalmology
- Refractive Error Research
Background:
- Preschool myopia is a significant risk factor for developing high myopia.
- Longitudinal data on preschool myopia progression has been limited.
- Understanding progression patterns is crucial for early intervention.
Purpose of the Study:
- To investigate the longitudinal changes in refractive error for children with preschool myopia.
- To identify key determinants associated with the progression of myopia in this age group.
Main Methods:
- Retrospective review of medical records from 495 patients with preschool myopia.
- Analysis of spherical equivalent (SE) refractive error changes over a median follow-up of 3.69 years.
- Linear mixed-effect regression models used to examine associations between SE change rate and initial patient characteristics.
Main Results:
- Average myopia progression was -0.59 D/year.
- 63.0% of children showed myopia progression (≤ -0.50 D/year), while 35.8% had stable refraction.
- Older age, female sex, and lower initial myopic SE were linked to faster progression.
Conclusions:
- Preschool myopia generally progresses, but a substantial portion of children maintain refractive stability.
- Initial patient characteristics significantly influence the rate of myopia progression in preschool-aged children.

Spherical coordinate systems are preferred over Cartesian, polar, or cylindrical coordinates for systems with spherical symmetry. For example, to describe the surface of a sphere, Cartesian coordinates require all three coordinates. On the other hand, the spherical coordinate system requires only one parameter: the sphere's radius. As a result, the complicated mathematical calculations become simple. Spherical coordinates are used in science and engineering applications like electric and...

Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

01:19Equivalent Capacitance
2.2K
Multiple capacitors can be connected in a circuit in series or parallel configuration. When the capacitor combination is connected to a battery, the potential drop across each capacitor and the magnitude of charge stored in the individual capacitor depends on the type of the connection. The capacitor combination is replaced by a single equivalent capacitor that stores the same amount of charge as the combination for a given potential difference.

01:26Pharmaceutical Equivalents
201
As defined by regulatory standards, pharmaceutical equivalents require generic drug products to have identical dosage forms and chemically identical active pharmaceutical ingredients (APIs). They must adhere to compendial or applicable standards for potency, content uniformity, disintegration times, and dissolution rates. In the case of modified-release dosage forms, variations in drug content are permissible as long as the delivered amount remains consistent with the innovator drug product.

01:15Systematic Error: Methodological and Sampling Errors
11.0K
In the case of systematic errors, the sources can be identified, and the errors can be subsequently minimized by addressing these sources. According to the source, systematic errors can be divided into sampling, instrumental, methodological, and personal errors.
Sampling errors originate from improper sampling methods or the wrong sample population. These errors can be minimized by refining the sampling strategy. Defective instruments or faulty calibrations are the sources of instrumental...

01:14Fundamental Attribution Error
13.8K
According to some social psychologists, people tend to overemphasize internal factors as explanations—or attributions—for the behavior of other people. They tend to assume that the behavior of another person is a trait of that person, and to underestimate the power of the situation on the behavior of others. They tend to fail to recognize when the behavior of another is due to situational variables, and thus to the person’s state. This erroneous assumption is...
