Retinal Fibre Layer Thickness Measurement in Normal Paediatric Population in Sweden Using Optical Coherence Tomography.

. To evaluate the correlation between peripapillary retinal nerve fibre layer (RNFL) thickness and both age and refraction error in healthy children using optical coherence tomography (OCT). . 80 healthy children with a mean age of 9.1 years (range 3.8 to 16.7 years) undergoing routine ocular examination at the orthoptic section of the Ophthalmology Department were recruited for this cross-sectional study. After applying cycloplegia, the peripapillary RNFL thickness was measured in both eyes using the Topcon 3D OCT 2000 device. . 138 eyes were included in the analysis. The average refractive error (SE) was +1.7 D (range -5.25 to +7.25 D). The mean total RNFL thickness was 105 m ± 10.3, the mean superior RNFL thickness was 112.7 m ± 16.5, and the mean inferior RNFL thickness was 132.6 m ± 18.3. We found no statistically significant effect of age on RNFL thickness (ANOVA, = 0.33, = 0.56). Refraction was proven to have a statistically significant effect (ANOVA, = 67.1, < 0.05) in RNFL measurements. . Data obtained from this study may assist in establishing a normative database for a paediatric population. Refraction error should be taken into consideration due to its statistically significant correlation with RNFL thickness.
