A systematic review of metabolomic studies on the mechanism of myopia / 中华实验眼科杂志

ABSTRACT

Myopia has become a global public health concern with its increasing prevalence.It is the interaction result of genetic and environmental factors.Exploration of the changes of metabolites in myopia is helpful to know new clues about its pathogenic mechanism.Metabolomics focuses on the integral analysis of all small molecular metabolites (relative molecular mass <1 000) which form a biological system and it is used as an effective tool to discover potential biomarkers.Metabolomic analysis of the myopic population could discover the metabolic changes related to myopia and screen the markers with potential biological significance, which can be used in the early diagnosis and treatment of myopia.It has been found that metabolites related to oxidative stress and inflammation play an important role in the development of myopia.Abnormal energy metabolism and amino acid metabolism are associated with myopic fundus changes.In addition, classical myopia-associated metabolites such as retinoic acid, dopamine and vitamin D, other metabolites such as melatonin, cyclic adenosine monophosphate and 5-hydroxy indole acetic acid, as well as multiple metabolic pathways such as fatty acid metabolism and mitochondrial metabolism are all closely related to myopia.This article systematically reviewed metabolomics researches on myopia, providing clues for better prevention and control of myopia in the future.
