TABLE 4.
Change in the Interferometric Pattern of the Tear Film for the Azithromycin (AZM) and Control Groups Between Before and After Treatment
AZM | Control | P | |
Interferometric pattern | |||
Effective | 10 (77%) | 2 (13%) | 0.002a |
Ineffective | 3 (23%) | 13 (87%) |
Eyes of interferometric class 2 (evaporative dry eye type) or class 1 (aqueous-deficient dry eye type) at baseline were categorized as showing an improvement (i.e., treatment was effective) if the interferometric pattern changed to class 0 (normal type).
The P value was determined with the Fisher exact test.
P<0.05.
