Comparison of meibomian gland dropout using two infrared imaging devices
Wong, Stephanie; Srinivasan, Sruthi; Murphy, Paul J.; Jones, Lyndon W. (Elsevier, 2018-11-07)Purpose To measure the degree of meibomian gland (MG) dropout in the lower eyelid determined by analysis of images obtained from the LipiView II (LVII) and the Keratograph 5M (K5M). Methods The inferior eyelid of each ... -
Corneal sensitivity after ocular surgery
Lum, Edward; Murphy, Paul J.; Corbett, Melanie (Wolters Kluwer, 2019-07-01)The cornea is densely innervated with free nerve endings to provide a high level of sensitivity to foreign bodies or noxious substances. They also provide trophic support to the tissues of the cornea and facilitate their ... -
Development of a new grading scale for tear ferning
Masmali, Ali M.; Murphy, Paul J.; Purslow, Christine (Elsevier, 2013-10-25)Purpose: This paper reports on the development of a new tear ferning (TF) subjective grading scale, and compares it with the Rolando scale. Method: TF patterns obtained from tear film samples collected from normal and dry ... -
Effect of ambient humidity on the Cochet-Bonnet aesthesiometer
Lum, Edward; Murphy, Paul J. (Springer Nature, 2018-06-19)Purpose: The Cochet–Bonnet (COBO) aesthesiometer is the current standard in corneal sensitivity assessment. This study investigates the influence of ambient room humidity levels on the stimulus force exerted by the ... -
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 ... -
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 ... -
