Increased intracranial pressure (ICP) has been suggested in legal settings as an alternative cause of retinal hemorrhages (RHs) in young children who may have sustained abusive head trauma. We assessed the prevalence and characteristics of RHs in children with increased ICP.
We conducted a prospective, multicenter study of children <4 years old with newly diagnosed increased ICP as determined by using direct measurement and/or clinical criteria. Infants who were premature, neonates, and suspected survivors of abusive head trauma were excluded on the basis of nonocular findings. Fundus examinations were performed; extent, number, and type of RH in each of 4 distinct retinal zones were recorded.
Fifty-six children (27 boys) were studied (mean age 15.4 months; range 1-43 months). All of the children had elevated ICP that required intervention. One child had papilledema. No child (0%; 95% confidence interval: 0%-6.4%) or eye (0%; 95% confidence interval: 0%-3.3%) was found to have an RH. Causes of increased ICP included hydrocephalus, intraventricular hemorrhage, congenital malformations, malfunctioning shunts, and the presence of intracranial space-occupying lesions.
Although acute increased ICP can present in children with a pattern of peripapillary superficial RHs in the presence of papilledema, our study supports the conclusion that RHs rarely occur in the absence of optic disc swelling and do not present beyond the peripapillary area in the entities we have studied.
在法律环境中,颅内压升高(ICP)被认为是可能遭受虐待性头部创伤的幼儿视网膜出血(RH)的另一种原因。我们评估了 ICP 升高儿童 RH 的发生率和特征。
我们进行了一项前瞻性、多中心研究,纳入了新诊断为 ICP 升高的<4 岁儿童,通过直接测量和/或临床标准确定。根据非眼部发现排除早产儿、新生儿和疑似虐待性头部创伤幸存者。进行眼底检查;记录每个 4 个不同视网膜区域中 RH 的程度、数量和类型。
共研究了 56 名儿童(27 名男孩)(平均年龄 15.4 个月;范围 1-43 个月)。所有儿童的 ICP 均升高,需要干预。1 名儿童有视盘水肿。没有儿童(0%;95%置信区间:0%-6.4%)或眼睛(0%;95%置信区间:0%-3.3%)出现 RH。ICP 升高的原因包括脑积水、脑室出血、先天性畸形、分流器故障和颅内占位性病变。
尽管急性 ICP 升高可能伴有视盘水肿的周边浅表 RH 模式出现在儿童中,但我们的研究支持这样的结论,即在没有视盘肿胀的情况下,RH 很少发生,并且在我们研究的实体中,RH 不会超出视盘周围区域出现。
