Is Your Doctor Prescribing Wrong Pink Eye Treatment?
USAgNet - 06/22/2017

A new study suggests that most people with acute conjunctivitis, or pink eye, are getting the wrong treatment. About 60 percent of patients are prescribed antibiotic eyedrops, even though antibiotics are rarely necessary to treat this common eye infection. About 20 percent receive an antibiotic-steroid eyedrop that can prolong or worsen the infection. The study is now online in Ophthalmology, the journal of the American Academy of Ophthalmology. This is the first study to assess antibiotic use for pink eye in a large, diverse segment of the United States. The findings are consistent with a nationwide trend of antibiotic misuse for common viral or mild bacterial conditions. It's a trend that increases costs to patients and the health care system and may promote antibiotic resistance. ­

Researchers at the University of Michigan Kellogg Eye Center looked at data from a large managed care network in the United States. They identified the number of patients who filled antibiotic eyedrop prescriptions for acute conjunctivitis. Then they evaluated the characteristics of patients who filled a prescription compared with those who did not.

Of approximately 300,000 patients diagnosed with acute conjunctivitis over a 14-year period, 58 percent filled a prescription for antibiotic eye drops. Among them, 20 percent filled a prescription for an antibiotic-steroid combination. Antibiotic-steroid drops are inappropriate for most patients with acute conjunctivitis because it may prolong or exacerbate certain types of viral infection.

Even more troubling, the authors found that the odds of filling a prescription depended more on a patient's socioeconomic status than the patient's risk for developing a more serious eye infection. For example, patients who wear contact lenses and those diagnosed with HIV/AIDS.

Pink eye affects 6 million people in the United States each year. There are three types: viral, bacterial, and allergic conjunctivitis. Antibiotics are rarely necessary to treat acute conjunctivitis. Most cases are caused by viral infections or allergies and do not respond to antibiotics. Antibiotics are often unnecessary for bacterial conjunctivitis because most cases are mild and would resolve on their own within 7 to 14 days without treatment.
