Ocular injuries caused by metal caps of carbonated mineral water bottles.

BACKGROUND

Bottles containing carbonated drinks are potentially hazardous to the eye. In this study, we aimed to document the clinical characteristics and visual outcomes in a series of patients with ocular injury from flying metal caps of carbonated mineral water bottles.

METHODS

Retrospective review of ocular injuries due to metal caps of carbonated mineral water bottles.

RESULTS

Sixteen eyes of sixteen patients were included in the study. All of the patients were male, with a mean age of 24 years. Ten of the patients had a history of using improper tools for bottle cap removal. The left eye was involved in twelve cases and the right eye in four cases. All patients had contusion-type closed-globe injury. Varying degrees of hyphema were observed in all patients, and vitreous hemorrhage was present in four. The visual acuity at the last follow-up was 20/20 in 15 of the patients.

CONCLUSION

The use of a bottle cap opener is essential for preventing ocular damage from pressed metal caps of carbonated drinks. In addition to popularising the use of screw cap bottles, warning labels that alert consumers about the possibility of eye injury should be placed on carbonated drinks with pressed metal caps.
