High myopia has become a global public health issue, posing a significant threat to visual health. There are still some problems in the process of diagnosis and treatment, including the definition of high myopia and pathological myopia, opportunities and challenges of artificial intelligence in the diagnosis and treatment system, domestic and international collaboration in the field of high myopia, the application of genetic screening in children with myopia and high myopia patients, and the exploration of new treatment methods for high myopia. Nowadays, myopia and high myopia show the characteristics of early onset age and sharp rise in prevalence, and gradually become the main cause of low vision and irreversible blindness in young and middle-aged people. Therefore, it is of great significance to accurately define high myopia and pathological myopia, combine artificial intelligence and other methods for screening and prevention, promote cooperation in different fields, strengthen gene screening for early-onset myopia and adopt new and effective ways to treat it.
