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.

Lamellar macular hole formation in a patient with diabetic CME treated by intravitreal bevacizumab injections.

A 49-year-old woman with a diagnosis of diabetic cystoid macular edema in both eyes presented with the appearance of a macular hole in the left eye 1 month after intravitreal bevacizumab injection. Optical coherence tomography demonstrated a lamellar macular hole in the left eye. Although vitreomacular traction and epiretinal membrane are the possible underlying causes for the development of lamellar macular hole formation in eyes with cystoid macular edema, in this case previous optical coherence tomography scans revealed the complete separation of the posterior hyaloid membrane and the absence of an epiretinal membrane. The exact mechanism involved in the progression of cystoid macular edema to lamellar macular hole and the contribution of the intravitreal bevacizumab injections to this transformation remain unclear.
