Abstract

VLBW infants are at risk of lesions including intraventricular haemorrhage and periventricular leucomalacia. Those with normal IQ still present with reading difficulties. Oculomotor performance was assessed on 14 VLBWs (IQ > 85) and 15 full-term age-matched controls. Anti-saccade errors were significantly higher for the VLBWs (78%) compared to full terms (62%) (P = 0.02). Smooth pursuit latency was longer for the VLBWs compared to the full terms. Greater anti-saccade errors may be indicative of a lesion affecting the frontal cortex or developmental delay. Oculomotor deficits in VLBW children may be associated with the higher incidence of reading difficulties that have been reported.

摘要

极低出生体重儿有发生包括脑室内出血和脑室周围白质软化等病变的风险。那些智商正常的儿童仍存在阅读困难。对14名极低出生体重儿（智商>85）和15名足月的年龄匹配对照者进行了眼球运动功能评估。与足月儿（62%）相比，极低出生体重儿的反向眼跳错误率显著更高（78%）（P = 0.02）。与足月儿相比，极低出生体重儿的平稳跟踪潜伏期更长。更高的反向眼跳错误率可能表明额叶皮质受到损伤或发育延迟。极低出生体重儿的眼球运动缺陷可能与已报道的较高阅读困难发生率有关。
