Abstract

Purpose :
To study the morphometry of optic disc parameters in eyes of healthy Mexican children using optical coherence tomography (OCT).

Methods :
Data were obtained from 219 eyes of children between 3 and 17 years old with no ocular pathology (117 girls and 102 boys). Children were distributed into three age groups: 3 to 7, 8 to 12 and 13 to 17 years. Each child was scanned using Stratus OCT (OCT-3; Carl Zeiss Meditec®) “fast optic disc” option.

Results :
The mean disc area was 2.87 + 0.54 mm2, the mean rim area was 1.99 + 0.71 mm2 and the mean rim volume was 0.62 + 0.47 mm3. The mean cup area and volume where 0.89 + 0.78 mm2 and 0.13 + 0.16 mm3 respectively. The mean horizontal cup disc ratio 0.55 + 0.20 µ and 0.47 + 0.19 µ the vertical. La the cup/ disc area ratio was 0.30 + 0.22 µ. There was no statistical difference between right and left eyes. The only gender difference was the rim volume parameter witch was statistically thicker in girls 0.73 + 0.55 mm3 than boys 0.50 + 0.31 mm3 (P= 0.003). The mean axial length (AL) was 23.11 + 1.23 mm, statistically grater between each age group, being the older children the ones with the longest eyes (P= 0.031, 0.000, 0.008 respectively). There was no statistical difference between age groups in the optic disc parameters.

Conclusions :
Rim volume was statistically thicker in girls. Even though there is a physiological increase in AL, the optic disc parameters showed no difference between the age groups. This study may be helpful for diagnosis and follow up of optic nerve pathologies in pediatric patients.
