Clinical Scorecard: Relationship Between Intraocular Pressure and Ocular Characteristics in Chinese Junior High Students Aged 14 to 18: Findings from the Anyang Childhood Eye Study

At a Glance

Key Highlights

• Mean IOP in right eye was 15.83 ± 3.11 mmHg among 1720 students aged ~16 years.
• IOP showed no significant sex differences despite males having greater corneal thickness and axial length.
• Myopia prevalence and severity were categorized and analyzed in relation to IOP and ocular biometric parameters.

Guideline-Based Recommendations

Diagnosis

• Measure IOP using non-contact tonometry with multiple readings averaged for accuracy in adolescent populations.
• Assess ocular parameters including CCT, AL, corneal curvature, and ACD using optical biometry devices.
• Perform cycloplegic autorefraction to accurately classify refractive errors in children and adolescents.

Management

• Monitor IOP and ocular biometric changes in myopic adolescents to identify potential risk for ocular diseases.
• Consider sex-based ocular structural differences when evaluating IOP and refractive status.
• Use standardized measurement times (e.g., morning hours) to reduce diurnal variation in IOP assessments.

Monitoring & Follow-up

• Regular ocular examinations in school-aged children to track IOP and refractive error progression.
• Longitudinal monitoring of axial length and corneal parameters to understand myopia development dynamics.
• Attention to potential hormonal or biomechanical factors influencing IOP differences by sex.

Risks

• Elevated IOP is associated with increased risk of glaucoma and may be linked to myopia progression.
• Structural ocular changes such as axial elongation in myopia may influence IOP measurements and ocular health.
• Sex-related differences in ocular biomechanics may affect susceptibility to ocular diseases.

Patient & Prescribing Data

Chinese adolescents aged 14 to 18 years undergoing ocular health assessment

No direct treatment data reported; findings support tailored monitoring strategies considering ocular biometric and sex differences to inform early interventions for myopia and glaucoma risk.

Clinical Best Practices

• Use non-contact tonometry with multiple readings averaged to measure IOP in adolescents.
• Perform comprehensive ocular biometry including CCT, AL, corneal curvature, and ACD for accurate ocular health assessment.
• Apply cycloplegic autorefraction to classify refractive errors precisely in pediatric populations.
• Schedule IOP measurements in the morning to minimize diurnal variation effects.
• Consider sex-based anatomical differences when interpreting IOP and ocular parameter data.
• Focus on early detection and monitoring of myopia progression and associated ocular changes in school-aged children.
