The tear film is a thin fluid multilayer left on the eye surface after a blink. A good tear film is essential for health and proper function of the eye, yet millions have a condition called dry eye disease (DED) that inhibits vision and may lead to inflammation and ocular surface damage.
There is little quantitative data about tear film failure, often called tear break up (TBU). Currently, it is not possible to directly measure important variables such as tear osmolarity with TBU.
We discuss automatic methods we have developed to extract data from video of healthy eyes, and to estimate important variables like osmolarity within regions of TBU. Not only is new data obtained, but far more data enabling statistical methods to be applied. So far, the methods provide baseline data for TBU in healthy subjects; future work will produce data from DED subjects.
Meet the Speaker
After a postdoc at National Institute of Standards and Technology, Dr. Braun started at the University of Delaware in the Department of Mathematical Sciences. Since 2002, he has collaborated with mathematicians, engineers, optometrists and ophthalmologists on studying tear film dynamics and ocular surface. Since then, he has supervised many award-winning students in this area, ranging from undergraduates to PhDs, with funding from NSF and NIH grants. After becoming the founding director of UD’s MS in Data Science program, his research increasingly includes data science for understanding the ocular surface, in the hope of aiding diagnosis and treatment of conditions like dry eye.
