Comparison of a new portable digital meniscometer and optical coherence tomography in tear meniscus radius measurement
Bandlitz, Stefan; Purslow, Christine; Murphy, Paul J.; Pult, Heiko (Wiley, 2013-10-07)Purpose: Non-invasive measurement of tear meniscus radius (TMR) is useful in the assessment of tear volume for dry eye diagnosis. This study investigates the agreement between a new, portable, slit-lamp mounted, digital ... -
Influence of Conjunctival Folds on Calculated Tear Meniscus Volume Along the Lower Eyelid
Bandlitz, Stefan; Purslow, Christine; Murphy, Paul J.; Pult, Heiko (Elsevier, 2016-05-03)Purpose: In calculating tear meniscus volume (TMV), tear meniscus height (TMH), radius (TMR) and cross-sectional area (TMA) are usually measured at the center of the lower lid margin, but lid-parallel conjunctival folds ... -
Lid-parallel conjunctival fold (LIPCOF) morphology imaged by optical coherence tomography and its relationship to LIPCOF grade.
Bandlitz, Stefan; Purslow, Christine; Murphy, Paul J.; Pult, Heiko (Elsevier, 2019-06)Purpose: Lid-parallel conjunctival folds (LIPCOF) are a well-accepted clinical sign in dry eye diagnosis. Commonly, LIPCOF is classified by grading the number of folds observed by slit-lamp microscope. This study investigated ... -
A New Portable Digital Meniscometer
Bandlitz, Stefan; Purslow, Christine; Murphy, Paul J.; Pult, Heiko; Bron, Anthony J. (Wolters Kluwer, 2014-01)Purpose: The aims of this study were (i) to develop a new portable slit-lamp mounted digital meniscometer (PDM) and (ii) to test its accuracy and repeatability compared to the existing Yokoi et al. videomeniscometer ... -
Relationship between Corneal Sensation, Blinking, and Tear Film Quality
Nosch, Daniela Sonja; Pult, Heiko; Albon, Julie; Purslow, Christine; Murphy, Paul J. (Wolters Kluwer, 2016-05-01)Purpose: To examine the possible role of corneal sensitivity and tear film quality in triggering a blink by investigating the relationship between blink rate, central corneal sensitivity threshold (CST), ocular surface ... -
The Relationship between Tear Meniscus Regularity and Conjunctival Folds
Bandlitz, Stefan; Purslow, Christine; Murphy, Paul J.; Pult, Heiko (Wolters Kluwer, 2014-09-01)Purpose: To investigate the capability of a new portable digital meniscometer (PDM) to measure tear meniscus radius (TMR) and tear meniscus height (TMH) at different locations along the lower lid and to evaluate relationships ...
