Summary

Trace elements are one of the indispensable substances in human body and play an important physiological role. Zinc is a trace element second only to iron in organisms, which is widely distributed in various systems and organs and plays an important biological role, and interacts with other trace elements such as copper and iron. With the improvement of detection methods, it is possible to detect the concentration of zinc and other trace elements in liquid samples. It is reported in the existing literature that there are significant changes in the concentration of trace elements in a variety of eye diseases. Our group intends to collect three kinds of samples (aqueous humor, blood and tears) of patients with primary glaucoma and age-related cataract who were treated in Sun Yat-sen Eye Center of Sun Yat-sen University from March 2020 to March 2021. Normal people with matched age and sex were recruited as normal control group (normal control group only collected blood and tear samples). Three methods (FI-ICP-MS, metabonomics and genomics) were used to study the concentration changes of patients with primary glaucoma in three kinds of body fluid samples, and the related factors were analyzed combined with clinical data, so as to provide a theoretical basis for studying the pathogenic mechanism and new prevention pathway of primary glaucoma.
