Insights
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.
Purpose:
To evaluate central corneal thickness in children.
Material And Methods:
Central corneal thickness was measured with the use of ultrasound pachymeter in 360 children aged 0-14 years.
Results:
Mean central corneal thickness was 537 microm after the birth and 567 microm in the age of 14 years. Wide differences between minimum and maximum recorded values were observed (410-650 microm) in first 2 years of life, and 420-640 microm in years 2-14.
Conclusions:
1. Mean central corneal thickness in children (even in small one's) does not differ significantly from adults and does not change with age. 2. Great differences between minimum and maximum recorded values were observed in children (especially in first two years of life), exceeding the range in adults. 3. IOP measurements in children should be corrected according to the results of central corneal thickness.
