Tainted eyedrops cause multiple deaths and blindness, CDC reports.

Contaminated eyedrops have been linked to four deaths and 14 cases of blindness, according to the Centers for Disease Control and Prevention (CDC). The CDC has identified 81 patients from 18 states who have been infected with a rare strain of a drug-resistant bacterium called P. aeruginosa. Most of the patients infected with the bacteria reported using artificial tears, with more than 10 different brands being named. The most commonly reported brand was EzriCare Artificial Tears, an over-the-counter product that is packaged in multidose bottles. The public is advised to stop using these products until they receive additional guidance from the agency or the Food and Drug Administration.
