Summary

This study mapped choroidal thickness in healthy children using enhanced depth imaging optical coherence tomography (EDI-OCT). Findings reveal a distinct choroidal thickness profile in children that changes with age.

Area of Science:

  • Ophthalmology
  • Pediatric Ophthalmology
  • Imaging Science

Background:

  • Choroidal thickness is a key indicator of ocular health.
  • Understanding normal choroidal development in children is crucial for identifying potential pathologies.
  • Enhanced depth imaging optical coherence tomography (EDI-OCT) offers high-resolution visualization of the choroid.

Purpose of the Study:

  • To establish normative choroidal thickness profiles in healthy children.
  • To investigate the spatial distribution of choroidal thickness across different retinal locations.
  • To explore the relationship between choroidal thickness and age in a pediatric population.

Main Methods:

  • Acquisition of horizontal and vertical EDI-OCT crosshair scans through the fovea in 48 healthy children.

  • Measurement of choroidal thickness at the fovea and at 1 mm and 3 mm intervals nasally, temporally, superiorly, and inferiorly.
  • Statistical comparison of choroidal thickness at various measurement points.

    • Main Results:

    • The mean subfoveal choroidal thickness was 348.4 ± 82.5 μm.
    • Choroidal thickness varied across different locations, with specific measurements provided for 1 mm and 3 mm intervals from the fovea.
    • A significant negative correlation was observed between subfoveal choroidal thickness and age.

    Conclusions:

    • EDI-OCT provides a detailed choroidal thickness profile in healthy children.
    • The observed choroidal thickness patterns suggest age-related changes and potential tissue redistribution in the pediatric choroid.
    • These normative data are valuable for pediatric eye care and research.
