Abstract
Purpose: Evaluating tear volume, as measured by the inferior central tear meniscus height (TMH), is a valuable clinical measure in the assessment of tear deficient dry eye (DE). A previous study (Bitton, Wittich 2014) found that an inferior gaze position increased the Schirmer score over that of superior gaze. Due to the invasive nature of the Schirmer strip coupled with the enhanced resolution of imaging techniques such as optical coherence tomography (OCT), it would be of clinical value to reassess if gaze position has an influence on the tear meniscus using an anterior segment OCT.
