眼钝挫伤是由外界机械性钝力引起,可造成眼内多种结构的改变,常常累及脉络膜、视网膜和视神经,可导致永久性视功能障碍。其中脉络膜破裂比较常见。脉络膜组织脆弱,血运丰富,且受限于视网膜和巩膜之间,易受钝力损伤。严重的眼球钝挫伤常引起脉络膜破裂,多发生于后极部,常伴有脉络膜出血,可造成不同程度视功能损害。如伴有出血, Eye blunt injury is caused by mechanical blunt force, can cause a variety of structural changes in the eye, often involving the choroid, retina and optic nerve, can lead to permanent visual dysfunction. Choroidal rupture is more common. Choroidal tissue fragile, rich blood supply, and limited by the retina and sclera, susceptible to blunt injury. Serious eye contusion often cause choroidal rupture, occurred in the posterior pole, often accompanied by choroidal hemorrhage, can cause varying degrees of visual impairment. If accompanied by bleeding,
