Summary
Central corneal thickness in children is similar to adults and stable with age. However, significant variations exist, especially in infants, necessitating adjustments for intraocular pressure (IOP) measurements.
Area of Science:
- Ophthalmology
- Pediatric ophthalmology
- Corneal science
Context:
- Accurate central corneal thickness (CCT) measurement is crucial for interpreting intraocular pressure (IOP) readings.
- Pediatric eye care requires specific considerations due to developmental changes.
- Limited data exists on CCT variability in young children.
Purpose:
- To evaluate central corneal thickness (CCT) in a pediatric population.
- To establish normative CCT values for children aged 0-14 years.
- To assess the age-related changes and variability in pediatric CCT.
Summary:
- This study measured CCT in 360 children (0-14 years) using ultrasound pachymetry.
- Mean CCT was 537 microm at birth and 567 microm at 14 years, showing stability with age.
- Wide CCT ranges (410-650 microm) were observed, particularly in the first two years of life.
Impact:
- Pediatric CCT does not significantly differ from adult values, but exhibits greater variability.
- The wide range of CCT in children, especially infants, highlights the need for age-specific IOP correction factors.
- Accurate IOP assessment in children may require CCT-based adjustments to account for corneal biomechanical differences.
