ABSTRACT
Tear film flow and stability studies were carried out in healthy population by Schirmer's test-1 and tear film break-up-time (BUT) measurements, respectively. The mean BUT observed was 13.87 +/- 4.79 seconds; however, in 22 percent of cases the values of BUT were even less than the lowest values laid down by various workers, from the Western countries. Maximum dry spots were located in the temporal quadrant.
