Abstract:
AIM:To investigate the difference of non - invasive tearfilm break - up time (NIBUT) by Keratograph 5M beforeand after forced eye opening in healthy individuals.METHODS: Prospective case self - control study. Fortynormal volunteers (79 eyes ) were enrolled. Tear filmimages were captured, non-invasive first tear film breakuptime(NIBUTf ), non- invasive average tear film breakuptime (NIBUTav ) and dry eye level were measured byKeratograph 5M automatically before and after forced eyeopening in each subject. For the first time, we checkedthe left eye after the right eye, and the second timechecked the right eye after the left eye.RESULTS: The average of NIBUTf and NIBUTav were9 18士5. 52s, 11. 74 士5. 59s respectively and percentage ofevery level of dry eye were 43% , 37% , 20% respectivelybefore forced eye opening. The average of NIBUTf andNIBUTav were 8. 91士5. 54s, 11. 76士5. 58s and percentage ofdry eye at different levels were 35% , 48% , 16%respectively after forced eye opening. There was nosignificant difference on NIBUT and dry eye level byOculus keratograph 5M in normal subjects (t = 0. 37, P =0 72; t = -0. 038, P = 0. 97; Z = -0. 42, P = 0. 68).CONCLUSION: There is no influence on NIBUT and dryeye level by detected Keratograph 5M before and afterforced eye opening in healthy subjects.
