Resumen
Este estudio establece datos normativos cruciales para el centro de acomodación (AF) y el centro de convergencia (VF) en niños ghaneses. Estos puntos de referencia son vitales para el diagnóstico y el manejo de las deficiencias visuales en esta población.
Área de la Ciencia:
- Oftalmología Oftalmología.
- Optometría pediátrica para niños.
- Salud Pública La salud pública.
Sus antecedentes:
- La literatura existente sobre las instalaciones de acomodación (AF) en las poblaciones africanas es limitada, centrándose principalmente en los estudiantes de secundaria.
- Hay una brecha significativa en los datos normativos para la facilidad de vergencia (VF) en niños africanos, lo que dificulta el diagnóstico y el manejo clínico.
- Este estudio aborda la necesidad de establecer puntos de referencia para la evaluación de la función visual en niños ghaneses.
Objetivo del estudio:
- Establecer datos normativos para instalaciones de acomodación (AF) en niños de 8 a 12 años.
- Determinar los datos normativos para la facilidad de vergencia (VF) en niños de 8 a 17 años.
- Proporcionar puntos de referencia para el análisis de casos, el diagnóstico y el manejo de la función visual en niños ghaneses.
Principales métodos:
- Una cohorte de 510 niños de 8 a 17 años se sometió a exámenes oculo-visuales completos.
- La facilidad de alojamiento (AF) se midió utilizando una lente de aleta ±2D durante 1 minuto.
- La facilidad de vergencia (VF) se midió utilizando un prisma de aleta de 3 bases en 12 bases durante 1 minuto.
Principales resultados:
- La mediana de instalación acomodable monocular (MAF) fue de 13 cpm (IQR: 4 cpm), con un rango normativo de 9-17 cpm.
- La facilidad acomodativa binocular mediana (BAF) fue de 13 cpm (IQR: 3 cpm), con un rango normativo de 9-14 cpm.
- La facilidad de vergencia mediana (VF) fue de 14 cpm (IQR: 4 cpm), con un rango normativo de 10-18 cpm.
Conclusiones:
- El estudio proporciona los primeros datos normativos para el centro de acomodación (AF) y el centro de convergencia (VF) en niños ghaneses.
- Estos hallazgos establecen estándares esenciales para la comparación clínica en el diagnóstico y manejo de la función visual.
- Los datos son específicos de niños ghaneses de edad similar y apoyan el análisis de casos audiológicos.

801
Aging is a complex biological phenomenon influenced by various processes that affect cellular and systemic functions. Several prominent theories attempt to explain its mechanisms, highlighting cellular limitations, oxidative damage, and hormonal changes as central factors in aging.
Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...

01:19The Effect of Aging on Tissues
3.6K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

01:11How Data are Classified: Categorical Data
45.1K
A variable, usually notated by capital letters such as X and Y, is a characteristic or measurement that can be determined for each member of a population. Data are the actual values of variables. They may be numbers, or they may be words. Datum is a single value.
Data are classified based on whether they are measurable or not. Categorical data cannot be measured; instead, it can be divided into categories. For example, if Y denotes a person's party affiliation, some examples of Y include...

38.4K
Data that are countable or measurable in specific units are called numerical or quantitative data. Quantitative data are always numbers. Quantitative data are the result of counting or measuring the attributes of a population. Amount of money, pulse rate, weight, number of people living in a town, and number of students who opt for statistics are examples of quantitative data.
Quantitative data may be either discrete or continuous. All quantitative data that take on only specific numerical...

01:29Drug Dosing: Infants and Children

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

01:09Changes in the Appendicular Skeleton with Age

The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
