Insights
Central choroidal thickness (CT) in children was measured using optical coherence tomography (OCT). This study found no correlation between CT and axial length, age, gender, or refractive error in healthy pediatric eyes.
Area of Science:
- Ophthalmology
- Pediatric eye care
- Optical coherence tomography
Background:
- Choroidal thickness (CT) is a key indicator of ocular health.
- Understanding normative CT values in children is crucial for diagnosing pediatric eye conditions.
- Optical coherence tomography (OCT) provides high-resolution imaging of the choroid.
Purpose of the Study:
- To establish a normative database for central choroidal thickness (CT) in a healthy pediatric population.
- To investigate the relationship between CT, axial length (AL), age, gender, and refractive error.
- To utilize enhanced depth imaging OCT for precise CT measurements in children.
Main Methods:
- A study of 137 healthy children (ages 4-18) was conducted.
- Measurements included dilated eye examination, cycloplegic refraction, and AL using an optical biometer.
- Central choroidal thickness (CT) and central foveal thickness (CFT) were assessed with Cirrus HD-OCT.
Main Results:
- The mean central CT was 388.2 ± 50.0 μm.
- No significant correlation was found between central CT and age, gender, axial length, or refractive error.
- The study established normative values for CT in a pediatric cohort.
Conclusions:
- The study provides a pediatric normative database for central choroidal thickness (CT) using enhanced depth imaging OCT.
- These normative data are valuable for diagnosing and monitoring pediatric retino-choroidal diseases.
- This research contributes to a better understanding of ocular development in children.
Purpose:
To investigate the association between central choroidal thickness (CT), axial length (AL), age, gender, and refractive error in a healthy pediatric population using optical coherence tomography (OCT).
Methods:
This institutional study involved 137 healthy children (57 boys, 80 girls) aged between 4 and 18 years. Each child underwent a dilated eye examination, cycloplegic refraction, and AL measurement using a Nidek AL-Scan optical biometer. The central foveal thickness (CFT) and CT were measured using Cirrus high definition (HD)-OCT. The right eye of each subject was selected for analysis.
Results:
The mean age of the children was 10.0 ± 4.7 years (range, 4-18 years). The mean spherical equivalent (SE) was -0.24 ± 1.24 diopters (D) (range, -2.00 D to +2.25 D). The mean AL was 23.1 ± 1.2 mm (range, 20-27 mm). The mean central CT was 388.2 ± 50.0 μm and was not correlated with age, gender, AL, or refractive error.
Conclusion:
The data provide a pediatric normative database of CT using enhanced depth imaging OCT. This information may be useful in the diagnosis and monitoring of retino-choroidal diseases in children.
