目的：报告了因汽车安全气囊造成的眼外伤及化学性烧伤。希望引起眼科同仁的高度重视．方法：４例病人均是进口高档小卧车，在发生碰撞时因汽车安全气囊高速膨胀打开及气囊破裂所致的眼损伤及化学烧伤．分析了汽车型号及种类，事故发生时的速度，眼损伤的类型和视力情况．结果：第一例病人为碱性化学性角膜炎伴虹膜根部离断及瞳孔括约肌破裂而造成瞳孔扩大；第二例病人为近视镜片致角巩膜板层撕裂伤；第三例病人为广泛角膜擦伤伴前房出血；第四例病人为视网膜水肿出血伴后极部脉络膜裂伤．结论：安全气囊能保护生命降低致伤率，但因气囊的冲击力量引起的机械损伤和气囊中强碱性气体导致的化学烧伤更要引起国内眼科医生的注意．
Purpose: To report ocular trauma and chemical burns due to a car’s airbag. Hope that the cause of eye colleagues attach great importance. Methods: All the 4 patients were imported high-grade small sleeping cars. During the collision, eye injuries and chemical burns caused by high-speed expansion of the airbags of the car and balloon rupture occurred. The types and types of vehicles, the speed at the time of the accident, the type of eye damage and the visual acuity were analyzed. Results: The first patient had basic chemical keratitis with iris root rupture and pupil sphincter rupture resulting in dilated pupils; the second patient had myopia and scleral lamellar laceration; the third patient had extensive cornea Abrasion with anterior chamber bleeding; the fourth case of patients with retinal edema and posterior pole rupture of choroidal hemorrhage. Conclusion: The airbag can protect the life and reduce the injury rate, but the mechanical damage caused by the impact force of the airbag and the chemical burns caused by the strong alkaline gas in the airbag should draw the attention of domestic ophthalmologists.
