Clinical Scorecard: Pediatric corneal data show geographic gaps

At a Glance

Key Highlights

• Central corneal thickness was assessed in 25 studies involving more than 28,000 children; findings on age- and sex-related differences were inconsistent.
• Studies generally found corneal curvature and diameter to be relatively stable during childhood, with some reported age- or sex-related variation.
• Studies examining racial and ethnic variation in central corneal thickness generally reported thinner corneas among Black children than White children; findings across other groups varied.
• Seventeen of 28 studies were conducted in Asia; 4 in North America; 2 each in Europe, Africa, and South America; and 1 in Australia. The authors noted limited representation of some populations.
• Measurement technologies and reporting practices differed across studies, complicating comparisons of reported values.

Guideline-Based Recommendations

Diagnosis

• The authors stated that pediatric corneal measurements should be interpreted in the context of the populations and measurement methods used to establish reference values.

Management

• The review assessed reference measurements and did not report disease-specific treatment recommendations.

Monitoring & Follow-up

• The authors called for longitudinal investigations of pediatric corneal measurements.

Risks

• Differences in measurement technologies, age classifications, demographic reporting, and eye laterality complicated comparisons.
• The predominance of Asian study populations and limited representation of other regions constrained generalizability.
• Most included studies were cross-sectional, limiting assessment of corneal development over time.
• The review was restricted to English-language publications, potentially excluding relevant evidence.

Patient & Prescribing Data

Healthy children younger than 18 years without additional impairments or comorbidities, as represented in the included studies.

The review assessed reference measurements and did not report prescribing or treatment data.

Clinical Best Practices

• The authors stated that pediatric corneal measurements should be interpreted in the context of the populations and measurement methods used to establish reference values.
• The authors reported that age- and sex-related findings varied across studies.
• The authors called for standardized measurement procedures and consistent reporting.
• The authors called for longitudinal studies involving more geographically and ethnically diverse pediatric populations.
