Abstract

Aim: To find the effect of blink rate and tear volume during jaw movement

Methodology: There are 50 subjects which were included in the study that are based on inclusion and exclusion criteria. First, we recorded Non-invasive breakup time, tear meniscus height, and Schirmer's test, that are followed by blink rate and inter blink interval which was recorded in video. Lastly, the parameters were taken without jaw movement and during jaw movement hence the results were compared.

Results: The report results were compared based on normal, reflex, and basal secretion with and without jaw movement and all of them are correlated.

There was a significant reduction in blink rate during jaw movement in all three conditions with which show 24.1 ± 10.33, 31.72 ± 13.9, 24.0 ± 12.97 respectively in without jaw movement to 17.5 ± 8.34, 25.72 ± 13.28, 18.46 ± 11.12 respectively during jaw movement.

There was a notable increase in inter blink interval values during jaw movement in all three conditions from 3.02 ± 1.33 sec, 2.3 ± 1.21 sec, 3.59 ± 2.93 sec respectively in without jaw movement to 4.32 ± 2.52 sec, 3.04 ± 1.68 sec, 3.59 ± 2.93 sec respectively during jaw movement.

There was a slight reduction in non-invasive tear break up time during jaw movement in all three conditions which appear to be 7.97 ± 1.38 sec, 6.76 ± 1.12 sec, 7.23 ± 1.31 sec respectively in without jaw movement and 6.06 ± 0.89 sec, 4.5 ± 1.23 sec, 5.84 ± 1.34 sec respectively during jaw movement.

There was pointless reduction in tear meniscus height during jaw movement in all three conditions with 0.34 ± 0.06 mm, 0.37 ± 0.08 mm, 0.35 ± 0.07 mm respectively in without jaw movement to 0.33 ± 0.06 mm, 0.35 ± 0.08 mm, 0.34 ± 0.08 mm respectively in during jaw movement.

Conclusion: From above data, we can conclude that there was remarkable reduction in blink rate, tear stability, tear secretion during jaw movement where as slightly increased inter-blink interval. Likewise, there were no change in TMH during jaw movement.
