What this trial studies
This observational cohort study focuses on children aged 8-15 years who have symptomatic convergence insufficiency. Participants will undergo visual training at the Tianjin Eye Hospital, and their health-related quality of life will be assessed using the EQ-5D-Y and CHU9D scales. The study aims to analyze the effectiveness of visual training in alleviating visual symptoms and improving overall quality of life for these patients. Data will be collected through self-assessment questionnaires completed by both patients and their guardians.
Who should consider this trial
Good fit: Ideal candidates are children aged 8-15 years with symptomatic convergence insufficiency who meet specific visual acuity and assessment criteria.
Not a fit: Patients with constant strabismus, significant refractive errors, or other ocular diseases may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could enhance the understanding of how visual training impacts the quality of life for children with convergence insufficiency.
How similar studies have performed: While there is limited information on similar studies, the approach of using visual training for convergence insufficiency has shown promise in other contexts.
