Abstract

Purpose: To investigate with HRT II and OCT (Optovue-100) normal parameters of the optic nerve head in full term children with high hyperopia and compare them to children with low hyperopia and emmetropia.

Methods: Optic nerve was examined with HRT II and peripapillary nerve fiber layer with Optovue-100 in 5-15 year old full term children with normal visual acuity and high hyperopia (≥ +3.0 dpt) and low hyperopia and emmetropia (< +3.0 to -1.0 dpt). Prior to study participation retinoscopy in cycloplegia was performed. One examination was performed on each eye. Optic nerve parameters of the both groups were compared with Wilcoxon-Mann-Whitney-Test. Eye with higher amount of hyperopia was included in the study.

Results: 35 children were included in the study, 17 of them were highly hyperopic. Mean refraction of the hyperopic eyes was +5.5 dpt ± 1.5 dpt, of the emmetropic eyes +0.65 dpt ± 1.2 dpt, (mean age of subjects 10 ± 2.7 years). There was no significant difference in peripapilary nerve fiber layer thickness (OCT) between the two groups. There was a significant difference in disc area (1.33 ± 0.36 mm2 vs. 1.79 ± 0.40 mm2, p=0.008) and rim area (1.09 ± 0.30 mm2 vs. 1.38 ± 0.34 mm2 , p=0.03) between the highly hyperopic and emmetropic group. No significant difference was found between the remaining HRT parameters including rim volume.

Conclusions: OCT in contrast to HRT II did not show any differences between children with high hyperopia and emmetropia. Optic discs in highly hyperopic eyes are more crowded as they are smaller in diameter but possess similar rim volume as emmetropic eyes.
