his study aims to evaluate macular and peripapillary retinal nerve fiber layer measurements in normal chil-

dren and their correlation with age, gender, laterality, refraction and axial length

Methods:

This was an observational cross sectional study among 100 eyes of 50 child (25 boys, 25 girls) aged

between 6 and 17 years. After detailed eye examination and axial length measurements, the children were

scanned using swept source optical coherence tomography (3D DRI OCT Triton [plus], Topcon Corporation,

Tokyo, Japan) to measure macular thickness, macular volume, peripapillary RNFL thickness and optic disc pa-

rameters.

Results:

Both eyes of fifty child were included in the study. Mean age was 10.96 ± 2.75 years, average spher-

ical equivalent refraction (SE) was 0.78±1.65 (−4.50 to +5.00) diopters and average axial length was 22.87

± 0.90 (20.99 to 24.67) mm. Average macular thickness was 276.41±17.8 μm, central macular thickness was

225.26±20.79 μm, mean macular volume was 7.84±0.48 mm3 and mean peripapillary RNFL thickness was

111.26±20.46 μm. Axial length showed positive correlation with age unlike negative correlation with spherical

equivalent. It also showed negative correlation with mean average RNFL thickness. Most of the parafoveal

region quadrants correlated positively with age unlike RNFL measurements that correlated negatively. Central

macular thickness values were significantly higher in males (p=0.001) but there was no difference between

male and female as regard RNFL thickness. Spherical equivalent didn’t show significant effect on studied pa-

rameters. Concerning the side of the eye, it had no statistically significant difference between both eyes but

good correlation.

Conclusion:

Normative paediatric SS-OCT data might facilitate use of SS-OCT for assessing childhood oph-

thalmic diseases. This study provides a paediatric normative database of SS-OCT peripapillary RNFL and mac-

ular data.
