Abstract：
To quantify the impact of prematurity on chromatic discrimination throughout childhood, from 2 to 15 years of age.
We recruited two cohorts of children, as part of the TrackAI Project, an international project with seven different study sites: a control group of full-term children with normal visual development and a group of children born prematurely. All children underwent a complete ophthalmological exam and an assessment of colour discrimination along the three colour axes: deutan, protan and trytan using a DIVE device with eye tracking technology.
We enrolled a total of 1872 children (928 females and 944 males) with a mean age of 6.64 years. Out of them, 374 were children born prematurely and 1498 were full-term controls. Using data from all the children born at term, reference normative curves were plotted for colour discrimination in every colour axis. Pre-term children presented worse colour discrimination than full-term in the three colour axes (p < 0.001). Even after removing from the comparison, all pre-term children with any visual disorder colour discrimination outcomes remained significantly worse than those from full-term children.
While colour perception develops throughout the first years of life, children born pre-term face an increased risk for colour vision deficiencies.

摘要：
目的：量化早产对整个儿童期色彩辨别的影响，从2岁到15岁。
方法：我们招募了两组儿童，作为TrackAI项目的一部分，一个具有七个不同研究地点的国际项目：一组视力发育正常的足月儿童的对照组和一组早产儿童。所有儿童都接受了完整的眼科检查，并沿三个颜色轴进行了颜色辨别评估：deutan，protan和trytan使用具有眼动追踪技术的DIVE设备。
结果：我们共招募了1872名儿童（928名女性和944名男性），平均年龄为6.64岁。在他们当中,374是早产儿童，1498是足月对照。使用所有足月出生的孩子的数据，在每个颜色轴绘制参考规范曲线以进行颜色区分。在三个颜色轴中，早产儿童的颜色辨别能力比足月儿童差（p<0.001）。即使从比较中删除，所有有任何视觉障碍的早产儿的颜色辨别结局仍然显著低于足月儿童.
结论：虽然色彩感知在生命的最初几年发展，早产儿面临色觉缺陷的风险增加。
