To determine if electroretinography is helpful in the work-up of children with the shaken baby syndrome.
Six children with retinal hemorrhages and the shaken baby syndrome underwent electroretinography (ERG). The ERGs of these six children were compared with six age-matched controls using the sign-rank test.
Neither the implicit time nor the amplitude of the white scotopic ERG response was significantly different between these patients and age-matched controls. Although the amplitude of the blue scotopic and 30 Hz flicker responses were attenuated (p < 0.05), the implicit times were not significantly different from controls. Three of the patients had serial ERGs recorded. The b-wave implicit time and amplitude improved in two of these patients. The ERG was helpful in distinguishing between a CNS and a retinal cause of visual loss in one child.
The ERG can be helpful in assessing retinal function in children with the shaken baby syndrome who have persistent visual impairment. In most cases, the ERG is not helpful in the initial assessment of children with the shaken baby syndrome.
确定视网膜电图是否有助于对患有摇晃婴儿综合征的儿童进行检查。
对6名患有视网膜出血和摇晃婴儿综合征的儿童进行视网膜电图（ERG）检查。使用符号秩检验将这6名儿童的ERG与6名年龄匹配的对照者进行比较。
这些患者与年龄匹配的对照者之间，暗视白光ERG反应的潜伏时间和振幅均无显著差异。尽管暗视蓝光和30Hz闪烁反应的振幅有所衰减（p<0.05），但其潜伏时间与对照者无显著差异。其中3名患者进行了系列ERG检查。这3名患者中有2名的b波潜伏时间和振幅有所改善。视网膜电图有助于区分1名儿童视力丧失的中枢神经系统原因和视网膜原因。
视网膜电图有助于评估患有摇晃婴儿综合征且存在持续性视力损害的儿童的视网膜功能。在大多数情况下，视网膜电图对患有摇晃婴儿综合征儿童的初始评估并无帮助。
