The disc\u2010center\u2010fovea angle (DFA) was used to evaluate ocular torsion using two different imaging modalities: optical coherence tomography (OCT) with a 55\u2010degree field of view (FV) and conventional fundus photography (CFP) with a 45\u2010degree FV. The values measured from both right and left eyes were combined to obtain a single value to compensate for the effect of head tilt during measurement.<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold> A total of 86 full\u2010term and 145 preterm children were enrolled in this study. The DFAs measured using OCT and CFP were \u221211.57\u00b0\u2009\u00b1\u20095.27\u00b0 and \u221212.07\u00b0\u2009\u00b1\u20095.66\u00b0 in the full\u2010term group and \u221210.64\u00b0\u2009\u00b1\u20095.40\u00b0 and \u221211.25\u00b0\u2009\u00b1\u20094.80\u00b0 in the preterm group, respectively. There were no significant differences between the results obtained from OCT and CFP in the two groups (<jats:italic>p<\/jats:italic> = 0.109 and <jats:italic>p<\/jats:italic> = 0.512, respectively). There was a strong correlation between OCT and CFP in all patients, with a Pearson\u2019s correlation coefficient of 0.74 and an intraclass correlation coefficient (ICC) of 0.74 (both <jats:italic>p<\/jats:italic> &lt; 0.001). Multivariate regression analysis showed that the average axial length (AXL) was associated with DFA.<\/jats:p><jats:p><jats:bold>Conclusions:<\/jats:bold> This study found a significant correlation between DFA measured using OCT and CFP, making either measurement modality feasible in pediatric populations. There was no significant difference in the DFA between full\u2010term and preterm children.
