Children with perinatal brain damage have a high prevalence of visual impairment. Stimulation of vision at a critical period can encourage brain plasticity and the recovery of impaired function.
The aim of our study was to investigate when is the critical period for visual stimulation in children with perinatal brain damage.
We compared 35 children within the first eight months of life (median age = 4 months) to 35 children aged between eight and thirty months (median age = 15 months), all with perinatal brain damage. All the children were attending an early intervention program at Mali dom, Zagreb, a rehabilitation centre for children with visual impairment. We compared the results from baseline and follow-up assessments of visual functions (grating acuity and contrast sensitivity). We also compared differences in change scores between the two groups.
Our results have shown that children who commence a visual stimulation program within the first eight months of life had more improvement in both visual functions. This improvement is statistically significant in visual acuity (p = 0.048).
These results indicate the importance of starting a visual stimulation program within the first eight months after birth.
围产期脑损伤的儿童视力障碍发生率较高。在关键期刺激视觉可以促进大脑可塑性和受损功能的恢复。
本研究旨在探讨围产期脑损伤儿童视觉刺激的关键期。
我们将 35 名 8 个月以下（中位年龄=4 个月）的儿童与 35 名 8 至 30 个月（中位年龄=15 个月）的儿童进行比较，这些儿童都患有围产期脑损伤。所有儿童均在萨格勒布马里 dom 接受早期干预计划，这是一个为视力受损儿童设立的康复中心。我们比较了基线和随访评估时视觉功能（光栅视力和对比敏感度）的结果。我们还比较了两组之间变化分数的差异。
我们的结果表明，在生命的前 8 个月内开始视觉刺激计划的儿童在两种视觉功能上都有更多的改善。这在视力方面有统计学意义（p=0.048）。
这些结果表明，出生后 8 个月内开始视觉刺激计划非常重要。
