To compare fluorescein tear break-up time (BUT) and noninvasive BUT measured using interferometry and corneal topography. We investigated 34 eyes of 34 patients with dry eye (mean age 39.2±8.3 years) and 16 eyes of 16 non-dry eye subjects (33.5±6.5 years). Tear film stability was measured using fluo...
