本研究为加纳儿童的适应性设施 (AF) 和融合设施 (VF) 建立了关键的规范性数据. 这些基准对于诊断和管理这一群体的视力障碍至关重要.
科学领域:
- 眼科医生 眼科 眼科
- 儿科光学测量 儿科光学测量
- 公共卫生 公共卫生
背景情况:
- 关于非洲人群住宿设施 (AF) 的现有文献有限,主要关注高中生.
- 对于非洲儿童的源设施 (VF) 的规范数据存在重大差距,这阻碍了临床诊断和管理.
- 这项研究解决了对加纳儿童视觉功能评估建立基准的需求.
研究的目的:
- 建立适应性设施 (AF) 对8-12岁儿童的规范性数据.
- 确定对8至17岁儿童的源设施 (VF) 的规范性数据.
- 为加纳儿童的病例分析,诊断和视觉功能管理提供基准.
主要方法:
- 一组510名8至17岁的儿童接受了全面的眼视检查.
- 住宿设施 (AF) 使用±2D镜头测量了1分钟.
- 使用3个基点在12个基点外的翻翼镜测量了Vergence设施 (VF) 1分钟.
主要成果:
- 单眼适应性设施 (MAF) 的中位数为13 cpm (IQR:4 cpm),规范范围为9-17 cpm.
- 双眼适应设施 (BAF) 的中位数为13 cpm (IQR: 3 cpm),规范范围为9-14 cpm.
- 平均结设施 (VF) 是每分钟14次 (IQR:每分钟4次),规范范围为每分钟10-18次.
结论:
- 这项研究提供了加纳儿童住宿设施 (AF) 和源设施 (VF) 的第一个规范性数据.
- 这些发现为诊断和管理视觉功能的临床比较制定了基本标准.
- 这些数据是针对相似年龄的加纳儿童的,支持听力学案例分析.

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...

How Data are Classified: Categorical Data
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...

Changes in the Appendicular Skeleton with Age
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...
