The Initiating Factors of Myopia Among Primary and Secondary School Students in Tianjin
NCT05637827 · Status: UNKNOWN · Type: OBSERVATIONAL · Enrollment: 200
Last updated 2022-12-05
Summary
There was a prospective cohort observational study. Forty hyperopic children, 40 myopic children and 120 emmetropia children were randomly selected from grade 1 to grade 3, and were followed up every six months for 3 years. All patients received cycloplegic refraction examination, ocular biological test, binocular visual function test and a questionnaire related to daily eye habits. A multi-level and multi-dimensional data analysis model was constructed to explore the possible factors affecting the occurrence and development of myopia in children.
