Optical coherence tomography had high reproducibility with reliable measurements in healthy children, according to a study.
The prospective, cross-sectional study included 100 healthy children with a mean age of 9.15 years who underwent a series of scans in one randomly selected eye with the Fourier-domain Cirrus HD OCT (Carl Zeiss Meditec).
One examiner conducted three scans that concentrated on the optic disc and three scans that concentrated on the macula. A second examiner performed a fourth scan in each area.
Intraclass correlation coefficients and coefficients of variation were used to depict intraobserver and interobserver repeatability.
Study results showed a mean retinal nerve fiber layer thickness of 99.53 µm and a mean macular thickness of 282.91 µm. All retinal nerve fiber layer and macular assessments were highly reproducible in the intraobserver and interobserver studies.
The authors said children older than 10 years had slightly better repeatability than those younger than 9 years.
