Lahey Clinic physician warns of danger from popular teen activity

Burlington, MA—An increasingly popular activity among school-aged children and teens can cause traumatic eye injury. The activity involves twisting and crushing an empty water bottle, with the cap loosened, until the cap flies off because of increased pressure. The force behind the cap may cause severe injury if it hits someone in the eye.

Lahey Clinic ophthalmologist Shiyoung Roh, MD, cites a recent case in which a teenager arrived with bleeding and increased pressure in the eye from the impact of a water bottle cap. The teen had severely diminished vision and as eye pressure increased from the injury, she required emergency surgery.

“Fortunately for this patient, she recovered her vision,” said Roh. “But the source of the injury--a water bottle cap ejected under pressure--warrants attention because of the increasing incidence of this activity among adolescents and school age children.”

An image and explanation of Roh's case can be seen the May 22, 2008, issue of the New England Journal of Medicine (
