概括

光学连贯性断层扫描 (OCT) 可以检测反复增加的内压力 (ICP),即使没有 papilledema. 这种非侵入性方法有助于监测视力缩患者的治疗反应.

科学领域:

眼科医生眼科眼科
神经学神经学
医疗成像医学成像

背景情况:

乳头是增加内压力 (ICP) 的常见指标.
检测ICP复发是具有挑战性的,特别是在预先存在的视神经缩的情况下,因为后视镜可能不会显示重新胀.
异常性水头症和腹腔关节分流并发症可能导致复发性ICP.

研究的目的:

在患有视力缩的患者中报告复发性内压升高 (ICP) 的病例.
突出光学连贯断层扫描 (OCT) 在检测ICP复发的微妙迹象方面的实用性.
强调国外和海外国家的作用,在监测治疗反应时,当 papilledema 没有临床明显.

主要方法:

一个23岁的女性病例报告,有异常性水头发病史和腹腔关节突变.
使用光学连贯断层扫描 (OCT) 来评估周周神经纤维层 (pRNFL) 的胀.
与临床症状相关的OCT发现,神经检查, fundus评估,MRI和脑脊液 (CSF) 压力测量通过腰部穿刺.

主要成果:

患者在OCT上出现了增加的ICP和PRNFL胀的症状,尽管视神经白,在后视镜检查中没有可见的 papilledema.
磁共振成像 (MRI) 最初没有显示增加ICP的迹象.
在腰部刺穿和脑液切除后,症状消失,视力敏度改善,pRNFL胀在OCT上减少.

结论:

光学连贯断层扫描 (OCT) 是一种敏感的,非侵入性的工具,用于检测反复增加的内压力 (ICP).
海外国外地区可以识别pRNFL的胀,表明ICP,即使存在视力缩和没有可见的 papilledema.
在怀疑高ICP和视力缩的患者中,OCT对于监测治疗疗效非常有价值.

Increased Intracranial Pressure l: Introduction

Increased Intracranial Pressure l: Introduction

Intracranial hypertension is a sustained elevation of intracranial pressure (ICP) above 22 mm Hg. In supine adults, normal ICP is ~7–15 mm Hg.The rigid, nonexpandable cranium contains three components—brain tissue, blood, and cerebrospinal fluid (CSF)—that total ~1,700 mL in a typical adult: 1,400 mL brain (~80%), 150 mL blood (~10%), and 150 mL CSF (~10%). According to the Monro–Kellie doctrine, total intracranial volume is effectively fixed. When one component...

Increased Intracranial Pressure ll: Pathophysiology

Increased Intracranial Pressure ll: Pathophysiology

Increased intracranial pressure (ICP) refers to a potentially life-threatening rise in pressure inside the skull. This usually happens when there is a major change in the volume of brain tissue, blood, or cerebrospinal fluid (CSF) — the three components inside the skull. According to the Monro-Kellie doctrine, if the volume of one component increases, the volumes of the other components must decrease to maintain normal pressure. If this does not happen, ICP rises.The process often begins...
