WASHINGTON >> U.S. officials are reporting two more deaths and additional cases of vision loss linked to eyedrops tainted with a drug-resistant bacteria.

The eyedrops from EzriCare and Delsam Phama were recalled in February, and health authorities are continuing to track infections as they investigate the outbreak.

In the latest government tally, 68 people got a diagnosis of infections from the bacteria, which now has caused a total of three deaths and eight cases of people losing their vision, the Centers for Disease Control and Prevention reported Tuesday. That’s up from one death and five cases of permanent vision loss reported last month.

The CDC said four people have undergone surgery to remove an eyeball because of the infections.

The outbreak is considered particularly worrisome because the bacteria driving it is resistant to standard antibiotics.
