How effective is azithromycin in treating dry eyes?

Azithromycin is fairly effective in improving the dryness and redness of the eye in people who have chronic dry eye syndrome that is caused by a condition called " meibomian gland dysfunction" (MGD). Azithromycin can sometimes be used in people with MGD who have failed conservative treatments.

In studies, azithromycin eyedrops were used once a day for a month. Oral azithromycin was taken once a day for 5 days. People who used either form of azithromycin had improvements in their dry eye symptoms and tear film quality. These improvements were greater than those seen in people using a different antibiotic, doxycycline. But the studies were small and more research is needed to be sure azithromycin is effective.
