Latex allergy associated with the latex cover on the TonoPen.

Abstract

To describe signs and symptoms of latex allergy associated with the use of the TonoPen (Mentor, Norwell, Massachusetts) in a patient with severe latex allergy. Case report. In a 13-year-old girl with a history of severe latex allergy, intraocular pressure was obtained with a TonoPen. TonoPen covers that contained latex induced agitation, bilateral conjunctival injection, eyelid erythema, and eyelid edema in this latex-allergic patient. Use of a fingertip from a sterile nonlatex glove provided accurate intraocular pressure measurements with the tono-pen, without a local or systemic reaction. In patients with latex allergies, TonoPen covers that contain latex may induce a substantial local and systemic reaction.
