一、钝挫伤视网膜改变视网膜震荡,包括震荡水肿和震荡坏死。1.视网膜震荡水肿(Berlin 水肿)眼球受到较轻钝挫伤,视网膜震荡水肿常常发生在受伤部位的对侧,如眼底的后极部;也可直接发生在受伤部位,常见于眼底的周边部.受震荡的部位视网膜水肿,出现边界不清的乳白色混浊,轻微时视网膜只有反光紊乱、透明度降低,轻微混浊。震荡水肿是可逆、暂时的,荧光血管造影常无异常发现.水肿消退后通常视力恢复正常,部分病例遗留轻度的色素紊乱和视力下降。目前,大多数作者都同意 Hirschberg(1875)的意见,即受震荡的组织发生血管舒
First, the blunt retina retina shock, including concussion and edema and shock necrosis. 1. Retinal shock edema (Berlin edema) The eye by a minor blunt traumatic, retinal edema often occurs in the contralateral side of the injured area, such as the posterior pole of the fundus; can also occur directly in the injured area, common in the periphery of the fundus. Retained areas of the affected area of the retina, opaque border opacity, mild retina only reflective disorder, reduced transparency, slightly cloudy. Oscillatory edema is reversible, temporary, fluorescent angiography often no abnormal findings .Eight usually returned to normal visual acuity subsided, in some cases left mild dyskinesia and vision loss. At present, most authors agree with Hirschberg (1875) that vasoactive tissue
