Measurement method of tear meniscus height based on deep …
2023年2月13日 · In traditional diagnostic methods for DED, Schirmer’s test, tear break-up time measurement, and ocular surface staining score are commonly used to qualitatively and quantitatively analyze the tear film (3, 4). Tear meniscus height (TMH) can be used to assess the tear volume and tear film status.
Evaluation of tear meniscus height using different clinical methods
Clinical relevance: The height of the tear meniscus (TMH) is a generally accepted method to evaluate tear film volume, especially in dry eye diagnoses and management. Background: The purpose of this study was to evaluate the ability of different methods to measure tear meniscus height accurately and repeatably.
Diagnostic Testing for Dry Eye - EyeWiki
Tear Meniscus Assessment: Tear meniscus can be observed over the lower lid margin after instillation of fluorescein vital dye using Cobalt blue filter. Its height can be roughly estimated compared to the slit lamp beam height although this method is not easily reproducible.
Diagnostic utility of tear meniscus height measurement using …
2024年10月28日 · To evaluate diagnostic utility of tear meniscus height (TMH) measurement using anterior segment optical coherence tomography (AS-OCT) for lacrimal passage disorder (LPD) in patients...
A deep learning approach for the quantification of lower tear meniscus ...
2021年7月1日 · 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.
Next-Generation Tear Meniscus Height Detecting and Measuring …
2024年9月1日 · This part contains eye, lower eyelid, and iris segmentation. In 20% of test data after automated cropping of the lower eyelid margin and upscaling by 8×, the appropriate tear meniscus height segmentation will be chosen and measured using a deep learning algorithm.
Tear meniscus measurement in the diagnosis of dry eye
Methods: Tear meniscus radius of curvature, height, width and cross-sectional area (TMC, TMH, TMW, XSA) were determined by photographing an optic section of the inferior tear meniscus (colored with a min volume of fluorescein) at 12 x magnification, and then scanning developed images into a computer analysis program. Fifteen dry eye subjects ...
Automated Measurement of Tear Meniscus Height with the Kowa DR-1α Tear ...
Interferometric fringe images of the lower tear meniscus are captured by DR-1α for measurement of meniscus height. Two parallel polarizers are installed to enhance the sharpness of the interferometric fringe colors and to reduce contamination by unintended reflected …
Feasibility of Tear Meniscus Height Measurements Obtained …
2024年2月1日 · The measurement process itself involved using a calibrated line, positioned at a 90° angle, to assess the height of the tear meniscus. This method allowed for accurate and reliable measurements, crucial for this study’s objectives.
The tear (lacrimal) meniscus height in human eyes: a useful …
Results: For elderly individuals, tTMH averaged 0.185+/-0.088 mm, while pTMH averaged 0.189+/-0.093 mm. The distribution of TMH measures however included a number of data sets with a much higher average, and which could be separated from the main group of data using cluster analyses approach (> 0.23 mm, P < 0.001).
