Amblyopia is a common cause of vision damage in children, and some aspects of its etiology are not clear. A number of mineral elements have important effects on the nerve and visual nerve systems. However, little is known about the relationship between amblyopia and nutritional mineral elements. In this study, hair samples were collected from 67 children with amblyopia and 57 age-matched control groups. The height and weight of each child was measured, and body mass index (BMI) was calculated. Mineral elements were determined by atomic absorption spectrometry and inductively coupled plasma-atomic emission spectrometry. The calcium and magnesium levels in the hair of amblyopic children were higher (p < 0.006), but the level of manganese were lower compared with those in the control groups (p < 0.006). Other elements measured were found to have an insignificant difference between the two groups (p > 0.006). The BMI of amblyopic children was higher (p < 0.001). These results show that mineral elements may play an important role in the visual development of children. Therefore, studies should pay more attention to investigating the impact of mineral elements on child vision.
弱视是儿童视力损害的常见原因，其病因的某些方面尚不清楚。许多矿物质元素对神经和视觉神经系统有重要影响。然而，弱视与营养矿物质元素之间的关系知之甚少。本研究采集了 67 例弱视儿童和 57 例年龄匹配对照组儿童的头发样本。测量了每个孩子的身高和体重，并计算了体重指数（BMI）。采用原子吸收光谱法和电感耦合等离子体原子发射光谱法测定矿物质元素。与对照组相比，弱视儿童头发中的钙和镁水平较高（p<0.006），但锰水平较低（p<0.006）。两组之间其他元素的测量值没有显著差异（p>0.006）。弱视儿童的 BMI 较高（p<0.001）。这些结果表明，矿物质元素可能在儿童视觉发育中发挥重要作用。因此，研究应更多地关注调查矿物质元素对儿童视力的影响。
