Tear Film Thickness Measured Using a Novel Technique
NCT01014780 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 40
Last updated 2010-10-11
Summary
The aim of this investigation is to determine the thickness of the human preocular tear film using a new method based on laser speckle. This will be a preliminary study to generate "normative" tear film thickness data in normal (i.e., non dry eye) and dry eye subjects in a clinic-based population. In addition, we will examine the short term (i.e., one week) repeatability of the method in a single setting.
The patients classified as having dry eye will also have their tear film thickness measured after instillation of an artificial tear. This will potentially reveal valuable data in retention of effect measured non-invasively as in prior studies that employed a fluorescein tracer.
