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.

Improvement of siderotic ERG.

For fear of endophthalmitis and siderosis, ferrous intraocular foreign bodies are usually removed as soon as they are discovered; markedly reduced, siderotic ERG changes are considered permanent. We report a patient who presented with a chronically retained intravitreal foreign body and significant clinical as well as electrophysiologic signs of siderosis. Only 3 months after surgery, the ERG showed almost complete recovery. If siderosis is not present, adequate and regular follow-up examinations may in certain cases substitute for immediate removal of chronically retained intraocular foreign bodies.

Intraocular foreign bodies: myths and truths.

Over the centuries, the management of eyes with intraocular foreign bodies (IOFB) has posed a special challenge to the physician, and the anxiety created by such injuries has never abated. During the past few decades, several new diagnostic tests, IOFB removal techniques, and methods to treat the complications of the injury have been introduced. Nevertheless, old habits die hard: many of the management options that used to be standard are not appropriate any more but have proved difficult to change. This article reviews over forty of these die-hard myths and confronts them with factual statements published in the peer-review international literature.

Internal limiting membrane removal for traumatic macular holes.

OBJECTIVE: To evaluate a new surgical technique for traumatic macular holes and to provide epidemiological information for such holes. MATERIALS AND METHODS: Vitrectomy with internal limiting membrane (ILM) removal but without adjuvant use on 17 consecutive eyes. RESULTS: The hole closed in 100% of eyes. Vision improved > or = 2 Snellen lines in 16 eyes (94%). The macula showed additional trauma-related damage in 10 eyes (59%). No permanent complication related to ILM removal was seen. Among 4440 eyes with contusion trauma in the United States Eye Injury Registry, the risk of macular hole formation is 9 times higher in eyes closed than with open globe injury (1.4% versus 0.15%). CONCLUSIONS: Without introducing special risks, removal of the macular ILM appears to be a highly successful surgical option in improving vision in eyes with traumatic macular holes. The majority of eyes benefit from ILM removal, even when additional traumatic macular pathology is present.
