Measurement method of tear meniscus height based on deep learning [PDF]

Frontiers in Medicine, 2023
Tear meniscus height (TMH) is an important reference parameter in the diagnosis of dry eye disease. However, most traditional methods of measuring TMH are manual or semi-automatic, which causes the measurement of TMH to be prone to the influence of ...

Impact of temporal tear meniscus height on the tear osmolarity measurements [PDF]

Scientific Reports
Tear hyperosmolarity plays a crucial role in initiation of inflammatory response and damage to ocular surface epithelia. Accurate measurement of tear osmolarity is essential for dry eye. This prospective observational and experimental study was conducted

Evaluation of tear meniscus height and lipid layer patterns of the tear film in domestic cats: An observational study [PDF]

Open Veterinary Journal
Background: Healthy vision in humans and animals requires a stable tear film. The environmental factor could affect the status of the tear film. Therefore, assessing the tear film in animals is essential to avoid visual system disturbance.

A Fully Automatic Estimation of Tear Meniscus Height Using Artificial Intelligence. [PDF]

Invest Ophthalmol Vis Sci, 2023
Accurate quantification measurement of tear meniscus is vital for the precise diagnosis of dry eye. In current clinical practice, the measurement of tear meniscus height (TMH) relies on doctors' manual operation. This study aims to propose a novel automatic artificial intelligence (AI) system to evaluate TMH.A total of 510 photographs obtained by the ...

Artificial intelligence-assisted tear meniscus height measurement: a multicenter study. [PDF]

Quant Imaging Med Surg
The tear meniscus height (TMH) is an important index for the diagnosis of dry eye. However, special inspection doctors are required to make rapid TMH measurements during outpatient examinations, which often leads to substantial measurement errors.

Lower tear meniscus height measured by optical coherence tomography in children

Ophthalmic 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.
