Mile Brujic, OD, and David Kading, OD, discuss the importance of examining the lid wiper region, especially in those with known or suspected dry eye disease. The lid wiper can be examined after lid eversion, but epitheliopathy in this region can only be appreciated with lissamine green or fluorescein staining. In turn, grading of lid wiper epitheliopathy can be used as a marker over time to track disease progression and response to therapy.
