Rapid onset of severe ocular injury after exposure to a button battery.

ABSTRACT

Button batteries are commonly used in many household electronic items and are a potential health hazard, especially in children. We present the case of a 2-year-old girl presented with swelling and redness of her right eye of 3 hours' duration. Examination revealed a button battery that had became lodged in the superior fornix of her right eye. After the intact battery was removed, the patient was found to have suffered an alkali burn to the underlying conjunctiva and sclera. The burn healed with symblepharon formation.
