OBJECTIVE: This study aims to explore the effects of eye exercises on the accommodative ability of Chinese school-aged children.
METHODS: This study used a convenience cluster sampling and selected 149 students from grades 2-5 in a Wenzhou primary school to participate in the intervention in June 2022. This study involved a one-month intervention teaching eye exercises using a composite feedback model. Assessments were made at 3 and 9 months post-intervention. Data collection occurred thrice, including a baseline and two follow-ups, measuring monocular and binocular accommodative facility, monocular and binocular accommodative amplitude, CISS scale, spherical equivalent refraction, and uncorrected visual acuity. Analysis used chi-square tests and generalized estimating equations to evaluate the exercises' effectiveness, with a significance threshold of P < 0.05.
RESULTS: 134 students completed the follow-up, including 61 females (45.52%). After teaching intervention, students showed significant improvements in the accuracy of manipulation, rhythm, acupoint location, strength effectiveness and rhythm of acupressure eye exercises (all P < 0.05), with increases of 10.37%, 13.03%, 16.96%, and 25.17%, respectively. Follow-up assessments revealed both monocular and binocular accommodative amplitude at T3 were significantly higher than at T1 and T2. Moreover, the binocular accommodative amplitude in the high-quality eye exercise group remained significantly higher than that in the low-quality group even(B=1.39,1.46, P < 0.01). Eye exercises could improve monocular and binocular accommodative amplitude in the short term(P < 0.05). High-quality eye exercises could alleviate visual fatigue (B=-2.00--3.49, both P < 0.05). However, eye exercises did not demonstrate any advantages in affecting spherical equivalent refraction or uncorrected visual acuity (P > 0.05).
CONCLUSION: Eye exercises can alleviate myopia-related symptoms in Chinese children aged 7 to 11 years. However, this study did not find that eye exercises effectively reduce the degree of myopia in children.
