Variability of the Analysis of the Tear Meniscus Height by Optical Coherence Tomography
Optometry and Vision Science, 2007ABSTRACT Purpose. Tear meniscus height (TMH) is an established parameter indicative of tear film volume and has recently been determined using an optical coherence tomographer (OCT). The purpose of this study was to evaluate the inter and intra observer variability in TMH assessment using OCT.

Comparison between graticule and image capture assessment of lower tear film meniscus height
Contact Lens and Anterior Eye, 2006To compare graticule and image capture assessment of the lower tear film meniscus height (TMH).Lower tear film meniscus height measures were taken in the right eyes of 55 healthy subjects at two study visits separated by 6 months. Two images of the TMH were captured in each subject with a digital camera attached to a slit-lamp biomicroscope and stored ...

Tear Meniscus Height, Lower Punctum Lacrimale, and the Tear Lipid Layer in Normal Aging
Optometry and Vision Science, 2006ABSTRACT Purpose. The purposes of this study are to investigate the tear meniscus height (TMH), lipid layer, and critical dimensions of the lower punctum lacrimale (DPL) in normal human subjects over a large age range; and to determine the shape and general characteristics of the lower punctum ...

Schirmer Test After Topical Anesthesia and the Tear Meniscus Height in Normal Eyes
Archives of Ophthalmology, 1979The height of the inferior tear meniscus was measured in 86 normal eyes. A value greater than 0.1 mm was obtained in 93% of the eyes that were studied. However, attempts to correlate meniscus height with subsequent Schirmer test results showed that these measurements varied randomly.

An adequate volume of tears is considered essential to prevent desiccation of the exposed ocular surface, especially in elderly individuals. Few assessments of tear meniscus height (TMH) have however been reported for elderly individuals.Close-up images of the lower marginal tear strip were obtained by videography over about 30 s in 56 elderly ...

Does the palpebral morphology influence the tear meniscus height between Caucasian and Asian eyes?
Optometry and Vision ScienceSIGNIFICANCE The tear meniscus height (TMH) along the lid margin is a clinical measure in the evaluation of patients with dry eyes and contact lens wearers. The morphology of the eyelid may differ among ethnic groups, potentially impacting the meniscus height, which can be useful for clinicians to optimize ...
