[Research progress on the relationship between circular RNAs and cataract].

Cataract is the leading cause of visual impairment and blindness on a global scale. The pathogenesis of cataract is not completely understood. Circular RNAs (circRNAs) are a special kind of non-coding RNAs with high stability and conservation. They are widely involved in a variety of biological processes and diseases. Abnormal expression of circRNAs can participate in the development of cataract, affecting the function of lens epithelial cells through interacting with proteins and sponging microRNAs. They are possible targets for cataract prevention and treatment. This article reviews the research progress on the role of circRNAs in the occurrence and development of cataract.
