摘要
Terson综合征是因外伤、颅内血管性病变等造成蛛网膜下腔出血后引起玻璃体积血的一种眼-脑综合征,目前蛛网膜下腔出血引起玻璃体积血的病理机制尚未阐明,主要有颅内出血直接进入眼内和颅压升高致眼内血管破裂出血两种学说.玻璃体出血可能是由于颅内压增高推动大量血液进入视乳头附近的玻璃体腔内所致,而眼内血液可能播散于内界膜下和视网膜内.深入了解Ter-son综合征的病理机制的研究现状,为进一步解答Terson综合症的病理机制提供研究思路,同时为该病治疗时机的选择和预后评估提供理论依据.
Vitreous haemorrhage occurring in association with subarachnoid haemorrhage is known as Terson＇s syndrome.It occurs most commonly due to ruptured intracranial aneurism,or after serious brain injury.The pathogenesis of vitreous haemorrhage remains controversial.The proposed theories include directly entering of intracranial hemorrhage and rupture of intraocular blood vessels caused by high intracranial pressure.The vitreous hemorrhage may be caused by a large amount of blood pushed by high intracranial pressure,entering the vitreous cavity near the optic disc.Inside the eye,the blood may spread sub-internal limiting membrane and intraretinally.The understanding of pathogenesis contributes to choosing the treatment strategies and predicting clinical outcomes of Terson＇s Syndrome.
