This study examined the relationship between tear film break–up patterns (TFBUP) and Schirmer’s Test scores in patients diagnosed with dry eye.
One–hundred and four patients with a reported history of dry eye underwent examinations including tear film break up time (TFBUT), TFBUP evaluation, and Schirmer’s Tests.
Mean Schirmer’s scores for each TFBUP are listed in the table below.
The distribution of Schirmer’s scores for each TFBUP is statistically different (p = 0.01). Fractured (p = 0.001), amorphous blob (p = 0.02), and wispy (p = 0.04) patterns had significantly higher Schirmer’s scores when compared to the linear pattern.
This data suggests a correlation between TFBUP and the Schirmer’s Test.
