Brief Summary

This trial is an observational cohort study. Patients aged 8-15 years with symptomatic convergence insufficiency and 150 patients with symptomatic convergence insufficiency who had not received visual training were selected from the Tianjin Eye Hospital Optometry Center and received 1 course of visual training treatment. Self-assessment and other assessments were combined, and the patient and guardian questionnaires were collected. The EQ-5D-Y and CHU9D scales were used to evaluate Chinese patients' health-related quality of life with symptomatic convergence insufficiency. The feasibility of the EQ-5D-Y and CHU9D scales in assessing the health-related quality of life of Chinese patients with symptomatic convergence insufficiency was analyzed. To assess the effectiveness of visual training on visual symptoms and improvement of quality of life in patients with symptomatic convergence insufficiency

Outcome Measures

Primary Outcomes (2)

  • Changes in EuroQol five dimensions questionnaire(EQ-5D-5L) score

    The EQ-5D-5L questionnaires were used to evaluate the quality of life scores of myopic patients.The health utility value can be calculated by the number of the answer to the question. 0 means death and 1 means complete health.

    The changes between baseline and 3 months

  • Changes in shortForm 6D(SF-6D) questionnaire score

    The SF-6D questionnaires were used to evaluate the quality of life scores of myopic patients.The health utility value can be calculated by the number of the answer to the question. 0 means death and 1 means complete health.

    The changes between baseline and 3 months
