Tear Meniscus Height (TMH)
Understanding Tear Meniscus Height (TMH)
What is TMH Analysis?
Tear meniscus height (TMH) analysis is a clinical method used to measure tear film volume, playing a crucial role in diagnosing and managing dry eye disease (DED). The tear meniscus forms at the edge of the eyelid and serves as a key indicator of ocular surface health. TMH is widely considered a reliable measure for evaluating tear production and tear film stability. A lower TMH often indicates insufficient tear production, which is a hallmark of dry eye conditions.
Challenges in TMH Analysis
While TMH analysis is a valuable tool for assessing dry eye disease, practical challenges remain in its routine clinical application. With a rising prevalence worldwide, DED presents significant socio-economic concerns and affects patients' quality of life.
Performing TMH analysis typically requires specialized instruments such as slit-lamps, corneal topographers, or optical coherence tomography (OCT). Although slit lamps are more accessible, they often lack the ability to precisely quantify TMH, making objective measurement difficult. Additionally, the availability of advanced diagnostic tools may be limited in resource-constrained environments, further hindering comprehensive dry eye assessments.

FH-POISE for TMH Analysis
FH-POISE provides integrated insights for TMH analysis by processing magnified images of the lower eyelid captured non-invasively using our ophthalmic cameras.
How FH-POISE Supports TMH Analysis
Insight-Based Measurement
It detects and quantifies TMH with high precision from captured images.
Objective Reporting
Provides clear, quantitative data on tear meniscus height to guide clinical decisions.
Enhanced Accessibility
Enables TMH assessment without the need for dedicated, high-cost instruments.
Consistent Monitoring
Supports longitudinal tracking of tear film changes for better management of dry eye disease.
By integrating advanced AI with accessible imaging technology, FH-POISE enables clinicians to conduct accurate TMH assessments, facilitating early diagnosis and improved patient care for dry eye disease.
