Clinical assessment of the lower tear meniscus height

open access: yesOphthalmic and Physiological Optics, 2009
Abstract Purpose:  Different values of the lower tear meniscus height (TMH) can be obtained depending on the method and technique of measurement employed. This study aimed to assess (1) differences between the absolute (TMH‐A), reflex (TMH‐R) and fluorescein (TMH‐F) lower tear meniscus heights,

Optimising the methodology for assessing tear meniscus height using digital imaging [PDF]

open access: yesContact Lens and Anterior Eye
To determine the optimum method for assessing tear meniscus height using digital imaging.The tear meniscus of 38 participants (mean age 32.5 ± 10.6 years, 45 % male) was video recorded three times, each for a period of five seconds following two natural blinks using the Oculus Keratograph 5M, first with infrared and subsequently with visible (white ...

Automated inferior tear meniscus height measurement in a sequence of video

open access: yes2012 IEEE-EMBS Conference on Biomedical Engineering and Sciences, 2012
Video analysis of the dynamics of the tear meniscus height (TMH) have been used in the diagnosis of dry eye. However, the existing techniques require substantial manual intervention. This research work aims to automate the process of estimating the change in the inferior TMH without manual intervention.

A deep learning approach for the quantification of lower tear meniscus height

Biomedical Signal Processing and Control, 2021
Abstract The quantification of the tear meniscus height can be helpful in the diagnosis of Dry Eyes Disease. This paper presents a method for automatic quantitation of lower tear meniscus height (TMH) with fully convolutional neural networks (FCNN) and investigate its performance and efficacy compared to manual measurements.

Lower tear meniscus height measured by optical coherence tomography in children

open access: yesOphthalmic and Physiological Optics, 2023
Abstract Introduction While optical coherence tomography (OCT) measurements of the lower tear meniscus height (LTMH) have been reported in adults, here we obtained LTMH measurements through Fourier Domain OCT in healthy children and compared these with values obtained in healthy adults.
