Evaluation of the Efficacy of Red Light in Adult Patients With High and Extreme Myopia
Starting soon · Not applicable
Conditions studied: Myopia
In brief
This study, led by Jie ying from the Ophthalmology Department of Beijing Tongren Hospital Affiliated to Capital Medical University, is a researcher-initiated clinical trial (IIT) designed to evaluate the therapeutic efficacy of low-intensity red light therapy in adult patients with high myopia (spherical equivalent ≤ -6.00D) and extreme myopia (spherical equivalent ≤ -10.00D). With the escalating global prevalence of high and extreme myopia-especially in East Asia including China-and pathological myopia becoming a leading cause of irreversible blindness in Chinese adults, red light therapy has shown promising effects in slowing myopia progression in children but lacks clinical evidence for adult populations, which constitutes the core rationale for this research.
