概括

在学龄儿童中,角膜厚度在三年内保持稳定,观察到的变化很小. 然而,与农村同学相比,城市学生的角膜变薄的情况更为明显.

科学领域:

眼科医生眼科眼科
角膜成像角膜成像
儿科眼睛健康儿科眼睛健康

背景情况:

关于儿童角膜厚度变化的纵向数据有限.
了解角膜发育和稳定性对于眼睛健康评估至关重要.

研究的目的:

研究中枢角膜厚度 (CCT) 的纵向变化及其影响因素在小学儿童.
为了评估三年内角膜厚度的稳定性.

主要方法:

一项纵向队列研究,涉及4432名学童 (8782只眼睛),分两个阶段 (2015年和2018年).
使用了 Scheimpflug 角膜成像,生物识别和折射测量.
使用通用估计方程 (GEE) 模型来分析角膜厚度的变化.

主要成果:

中央角膜厚度 (CCT) 的三年平均变化为-0.58微米.
角膜厚度的变化因区域而异:上角膜增加,下角膜减少.
城市学生比农村学生显示出更大的CCT稀释 (p < 0.001).
基线CCT,前腔深度,角膜直径,BMI和轴长是影响CCT变化的重要因素.

结论:

临床上,CCT的三年变化是可以忽略不计的,这表明学童的角膜稳定性.
角膜稀释在城市学生中更为明显.
诸如基线CCT,轴长和BMI等因素会影响角膜厚度随时间变化.

关键词:

Longitudinal Research

Longitudinal Research

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...
