Ocular Surface Disease Index (OSDI). OSDI was evaluated at baseline and after 1 week, 1, 3, and 6 months in patients receiving either true (n=24) or sham (n=25) acupuncture treatment. True acupuncture treatment significantly improved OSDI when compared to sham treatment only after 6 months (*p=0.04). Also, OSDI scores significantly improved 1 week after true acupuncture treatment and continued to improve (†p<0.05).
