Abstract

Objective: This study aimed to measure the peripapillary retinal nerve fiber layer (RNFL) thickness using spectral-domain optical coherence tomography (SD-OCT) in normal Iranian children aged below 18 years.

Methods: Peripapillary RNFL imaging was performed in the right eye of normal Iranian children aged below 18 years using Spectralis SD-OCT (Heidelberg Engineering; Vista, CA). The effects of age, gender, cup-to-disc ratio, and spherical equivalent (SE) on global and sectoral RNFL thicknesses were evaluated.

Results: A total of 115 eyes were imaged. Approximately 51 (44.3%) of the cases were female children. The mean age was 12.44 ± 2.52 years. The SE of refractive error was 0.39 ± 1.38 diopters (range: -3.00 to +4.5 D). The RNFL thickness measurements in the superior, inferior, nasal, and temporal quadrants were 129.25 ± 14.52, 128.16 ± 13.46, 76.76 ± 10.58, and 69.58 ± 9.94 μm, respectively. The global RNFL thickness was 101.01 ± 7.74 μm. In both univariate and multiple regression analyses, SE was the only determinant of RNFL thickness (all P values < 0.05).

Conclusions: OCT analysis can effectively measure RNFL thickness in children, and SE is the only determinant of RNFL thickness in normal Iranian patients aged below 18 years.
