Abstract：
Cataracts are one of the most common causes of effective vision loss. Although most cases of cataracts are related to the ageing process, identifying modifiable risk factors can prevent their onset or progression. Many studies have suggested that micro and macroelement levels, not only in blood serum but also in the lens and aqueous humour, may affect the risk of the occurrence and severity of cataracts. This systematic review aims to summarise existing scientific reports concerning the importance of trace elements in cataractogenesis. Many authors have pointed out elevated or decreased levels of particular elements in distinct ocular compartments. However, it is not known if these alterations directly affect the increased risk of cataract occurrence. Further studies are needed to show whether changes in the levels of these elements are correlated with cataract severity and type. Such information would be useful for determining specific recommendations for micronutrient supplementation in preventing cataractogenesis.
摘要：
白内障是有效视力丧失的最常见原因之一。尽管大多数白内障病例与衰老过程有关，确定可改变的危险因素可以防止其发作或进展。许多研究表明，微观和宏观元素水平，不仅在血清中，而且在晶状体和房水中，可能会影响白内障发生和严重程度的风险。本系统综述旨在总结有关微量元素在白内障发生中的重要性的现有科学报告。许多作者指出了不同眼室中特定元素的水平升高或降低。然而,目前尚不清楚这些改变是否直接影响白内障发生风险的增加。需要进一步的研究来显示这些元素水平的变化是否与白内障的严重程度和类型相关。这些信息将有助于确定在预防白内障发生中补充微量营养素的具体建议。
