Optimising the methodology for assessing tear meniscus height using digital imaging [PDF]
Contact Lens and Anterior EyeTo 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
2012 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, 2021Abstract 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.

Agreement of Tear Break-Up Time and Meniscus Height between Medmont E300 and Visionix VX120+
Applied Sciences (Switzerland), 2022 The goal of this study was to analyze the agreement between the Medmont E300 and the Visionix VX120+ systems in terms of non-invasive tear break-up time (NIBUT) and tear meniscus height (TMH) measurements. A total of 60 eyes (30 healthy subjects) were enrolled.

Interobserver variability of an open-source software for tear meniscus height measurement
Contact Lens and Anterior Eye, 2016Different values of the lower tear meniscus height (TMH) can be obtained depending on the method and technique of measurement employed. The aim of this study was to analyse the interobserver variability of a method for measuring TMH by using an open source software.On a group of 176 subjects, two videos of the central lower tear meniscus, first under ...

The Height and Radius of the Tear Meniscus and Methods for Examining These Parameters
Cornea, 2000To investigate the relationship between the radius of tear meniscus curvature (TMR) and tear meniscus height (TMH).Twenty-nine eyes of dry-eye patients (all left eyes; two males, 27 females, aged 26 to 85 years [mean +/- SD; 60 +/- 14.4]) were enrolled in the study.

Quantitative Evaluation of Tear Meniscus Height From Fluorescein Photographs
Cornea, 2007To describe a method of quantifying the tear meniscus height (TMH) and using these values to diagnose patients with dry eye.Thirty-eight eyes of 19 healthy subjects and 14 patients diagnosed with dry eye were studied. Each eye received 2 microL of 1% fluorescein-sodium solution in the conjunctival sac, and digital photographs were taken of the external
