What is it about?
The Schirmer test measures the volume of tears in the assessment of dry eye. As no standard exists with respect to eye gaze with the test, this study measured the Schirmer test under three eye positions, namely straight, up and down gaze, finding that the latter gave greater Schirmer scores.

Why is it important?
By establishing standardized comparison parameters, researchers and clinicians will have an easier time comparing their results and working towards evidence-based practice.
Perspectives
This was one of my first collaborative projects with Dr Bitton, and I am still learning lots about dry eye treatments and anterior segment research.
