This population-based study evaluated motion and form perception in 71 children born extreme premature (EPT; < 27 gestational weeks), aged 6.5 years, as compared to a matched group of 79 control children born at term. Motion and form perception were evaluated by motion coherence and form coherence tests. The EPT group showed a poorer performance on both tasks as compared to the control group. However, after controlling for IQ and visual acuity, the EPT group showed only a significant deficit in motion perception. No association was found between motion perception accuracy and gestational age, previous retinopathy of prematurity, or previous intraventricular hemorrhage in the EPT group. The results highlight the long-term motion perception deficits in children born EPT.
本基于人群的研究评估了 71 名极早产（EPT；<27 孕周）儿童和 79 名足月出生对照儿童在 6.5 岁时的运动和形态感知能力。运动和形态感知能力通过运动连贯性和形态连贯性测试进行评估。与对照组相比，EPT 组在两项任务中的表现均较差。然而，在控制智商和视力后，EPT 组仅在运动感知方面存在显著缺陷。在 EPT 组中，运动感知准确性与胎龄、既往早产儿视网膜病变或既往脑室出血之间没有关联。研究结果突出了极早产儿长期存在的运动感知缺陷。
