Three patients who were involved in road traffic accidents and sustained seat belt related injuries developed a retinal angiopathy characterised by retinal haemorrhage, oedema and focal ischaemia. Significant unilateral visual loss (2/60 - 6/18) was reported 1-48 hours following injury and central or paracentral annular scotomata were present. Although there was good recovery of visual acuity all patients had permanent scotomata, colour vision defects and loss of contrast sensitivity. Residual retinal microvascular and haemodynamic changes were noted on fluorescein angiography and the visually evoked responses were uniformly depressed. The structural and functional alterations in the retina of patients who have sustained seat belt injuries have important medico-legal implications.
三名在道路交通事故中受伤且有安全带相关损伤的患者出现了以视网膜出血、水肿和局灶性缺血为特征的视网膜血管病变。受伤后1至48小时报告有明显的单眼视力丧失（2/60 - 6/18），并存在中心或旁中心环形暗点。尽管所有患者的视力都有良好恢复，但均有永久性暗点、色觉缺陷和对比敏感度丧失。荧光素血管造影显示视网膜微血管和血流动力学有残留变化，视觉诱发电位均降低。遭受安全带损伤的患者视网膜的结构和功能改变具有重要的法医学意义。
