Abstract：
Terson syndrome (TS) describes the presence of intraocular haemorrhage in patients with intracranial haemorrhage or traumatic brain injury. The aetiology of TS is controversial as an anatomical conduit between the vitreous humour and subarachnoid space remains contested. We herewith present a case of primary vitreous haemorrhage with secondary intracranial extension into the ventricles. Cranial CT demonstrates blood within the left optic nerve and chiasm but not within the subarachnoid space. This unusual phenomenon, which has not been reported before, may be described as \'Terson syndrome in reverse\'. We explore mechanisms by which blood within the globe may track into the ventricular system, contextualising recent advances in the understanding of ocular-intracranial fluid transport.
摘要：
Terson综合征（TS）描述了颅内出血或创伤性脑损伤患者眼内出血的存在。TS的病因是有争议的，因为玻璃体液和蛛网膜下腔之间的解剖学管道仍然存在争议。我们在此介绍一例原发性玻璃体出血，继发颅内扩展到心室。头颅CT显示左视神经和交叉内的血液，但不在蛛网膜下腔内。这种不寻常的现象,以前没有报道过，可能被描述为“相反的特森综合征”。我们探索了全球血液可能进入心室系统的机制，背景技术在理解眼-颅内液体运输方面的最新进展。
