外伤性视网膜血管病(Purtscher)是一种与头部外伤有关,表现特异性眼底改变的疾病。多为双眼,单眼者极罕见。作者报导1例单眼患者。男性44岁,地震时胸部挤压伤、头及腰部挫伤,后左眼视力差。视力右1.5,左0.3。左眼底除小动脉硬化外,视乳头附近约4PD范围内散在有形态及大小不等的絮状白斑,位于神经纤维层内,未发现出血。眼底荧光造影动脉期无异常,毛细血管期可见与白斑大小相符的血管闭塞区,其周围一部分毛细血管扩张,一到静脉期周边部血管即有渗漏;后期见白斑处有荧光增强。右眼底除有小动脉硬化外,未见异常。伤后1周视力恢复到0.7。眼底白斑较前缩小,境界清晰,视乳头附近出现线状及火焰状小出血。第2周视力达0.9,视网膜白斑及出血有 Traumatic retinal vascular disease (Purtscher) is a disease associated with traumatic head injury, the performance of specific fundus changes. Mostly eyes, monopoles are extremely rare. The authors report 1 patient with monocular. 44-year-old male, chest crush injury, head and lumbar contusion, poor left eye vision. Right vision 1.5, left 0.3. In addition to small arteriosclerosis in the left fundus, flocculent leukoplakia scattered in the range of about 4 PD near the optic nerve, in the shape and size, was located in the nerve fiber layer and no bleeding was found. Fundus fluorescein angiography arterial phase without abnormal capillary phase can be seen consistent with the size of white blood vessels in the occlusion area, the surrounding part of the telangiectasia, one to the peripheral venous vascular leakage; the late see the white spots have enhanced fluorescence. In addition to the right retinal arteriosclerosis, no abnormalities. Visual acuity recovered to 0.7 at 1 week after injury. Ocular white spots smaller than before, the realm of clear, near the optic nerve appeared linear and flaming small hemorrhage. Week 2 visual acuity of 0.9, retinal leukoplakia and bleeding
