科学领域:

  • 眼科医生 眼科 眼科
  • 新生儿科学 新生儿科学
  • 神经科学是一个神经科学.

背景情况:

  • 过早出生的婴儿面临过早生育的视网膜病变的风险,影响视网膜功能.
  • 电网膜学 (ERG) 用于测量视网膜功能异常.

研究的目的:

  • 在早产婴儿中记录非侵入性的闪ERG.
  • 为了比较中度和非常/极度早产婴儿之间的视网膜功能.

主要方法:

  • 40名中度早产和40名非常/极度早产婴儿接受了闪ERG记录.
  • 使用带有皮肤电极的RETeval®设备用于闭眼记录.
  • 呈现了28.3 Hz和不同强度 (3-50 cd•s/m2) 的刺激;峰值时间和振幅是主要的终点.

主要成果:

  • 在大多数婴儿中,闪ERG是可记录的,最好的可复制性在30cd•s/m2.
  • 随着刺激强度的增加,ERG振幅也会增加.
  • 在最高刺激水平 (p<0.001) 上,在非常/极度早产婴儿中观察到显著更大的幅度.

结论:

  • 在早产婴儿中收集闪ERG数据是可行的.
  • 在极度早产的婴儿中没有发现视网膜反应减少的证据.
  • 在非常/极度早产的婴儿中,较高的振幅可能表明视觉输入驱动的视网膜发育加速.
