Airbags and eye injuries: epidemiology, spectrum of injury, and analysis of risk factors.
Although airbags measurably reduce the overall risk of injury to adults (including eye injury), and death from motor vehicle accidents, injuries attributed to airbag deployment have been reported. To identify reported cases of ocular trauma related to airbag deployment, a MEDLINE search from 1991 to 2000 was performed. A total of 263 injuries in 101 patients were identified. Patient demographics, details of the accident, specific ocular structures injured, and visual outcomes when available where tabulated and analyzed. The most common of these affect the eyes. Damage to the orbit and virtually every ocular and adnexal structure has been seen. Although most injuries are self-limited and do not significantly compromise vision, some result in severe, permanent visual loss. Most common is damage to anterior structures due to either blunt, contusive forces and/or chemical injury. Posterior segment trauma is less common but generally more visually devastating because of the involvement of the retina or optic nerve. Data are not available to determine whether the wearing of eyeglasses or previous intraocular surgery affects the nature, severity, or outcome of these injuries. Awareness of the spectrum of airbag-associated ocular trauma will help physicians recognize these problems early and optimize their management. Data derived from analyses of these injuries will be critical to the development of safer, more effective devices.
