Summary
A 16-week recess-based ocular muscle regulation training program (OMRTP) improved adolescent vision. This program led to better uncorrected visual acuity and spherical equivalent refraction in students.
Area of Science:
- Ophthalmology and Vision Science
- Adolescent Health
- Preventive Medicine
Background:
- Adolescent vision health is crucial for academic performance and overall well-being.
- Uncorrected refractive errors and suboptimal visual acuity are prevalent issues among school-aged children.
- Ocular muscle regulation training programs offer a potential non-invasive intervention for visual function enhancement.
Purpose of the Study:
- To evaluate the efficacy of a 16-week recess-based ocular muscle regulation training program (OMRTP).
- To assess the impact of OMRTP on uncorrected visual acuity (VA) and noncycloplegic spherical equivalent (SE) in adolescents.
- To determine if OMRTP provides functional visual benefits compared to standard vision health education.
Main Methods:
- A school-based controlled study involving 200 Grade 10-11 students (U15-U16) in Huzhou, China.
- Participants were assigned to an experimental group (EG, n=100) receiving OMRTP or a control group (CG, n=100) receiving routine vision health education.
- Visual acuity and noncycloplegic spherical equivalent were measured at baseline and post-intervention (17 weeks), with analysis using difference-in-differences (DiD) and linear mixed-effects models.
Main Results:
- Baseline VA and SE were comparable between the experimental and control groups.
- The experimental group showed statistically significant improvements in both noncycloplegic spherical equivalent (DiD ranging from 0.210 D to 0.358 D) and visual acuity (DiD ranging from 0.074 to 0.156) compared to the control group.
- Mixed-effects models confirmed a significant group × time interaction for both SE (P < 0.001) and VA (P < 0.001), indicating a robust intervention effect.
Conclusions:
- A 16-week recess-based OMRTP is effective in improving uncorrected visual acuity among adolescents.
- The OMRTP intervention led to short-term functional changes in noncycloplegic spherical equivalent refraction.
- Recess-based OMRTP presents a viable strategy for enhancing visual function in school-aged populations.

Accessory Structures of the Eye
Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...
Muscles of the Eye
The muscles of the eye are sophisticated structures that control eye movement and focus, allowing for the precise and rapid adjustments necessary for vision. The human eye is controlled by ten muscles — six extraocular muscles, three intraocular muscles, and one primary eyelid retractor muscle.
Extraocular Muscles
The six extraocular muscles surround the eyeball and control its movements. They are responsible for a wide range of eye motions, including looking up, down, left, right, and rotating...
