“…In recent years, the clinical application of time domain anterior segment optical coherence tomography has dramatically increased the objectivity of tear meniscus measurements, including TMH and the tear meniscus area (TMA) [ 6 – 14 ]. The SS-1000 (Tomey Corp, Nagoya, Japan) swept-source OCT (SS-OCT) device, which was designed specifically for imaging the anterior segment, uses a wavelength of 1310 nm and allows for cross-sectional analysis as well as 3-dimensional analysis of the anterior segment of the eyes—thus enabling the measurement of TMH and TMA as well as tear meniscus volume via the use of an invisible long-wavelength light source that does not cause photophobia [ 10 , 13 ].…”

PurposeTo investigate the usability and the reproducibility of the tear meniscus values via swept-source optical coherence tomography (SS-OCT) and the conventional slit lamp microscope method with a graticule.MethodsThe right eye was examined in 90 healthy adult subjects who were grouped according to age (group 1: 20–39 years; group 2: 40–59 years; group 3: ≥60 years). The tear meniscus height (TMH) and tear meniscus area were measured using SS-OCT and TMH by the slit lamp microscope method. The reproducibility of each method was calculated using intraclass correlation coefficients (ICCs) in additionally enrolled 30 healthy young subjects. We also evaluated TMH at 3 mm from the corneal center in both temporal and nasal directions using SS-OCT.ResultsThe mean of the TMH values measured by SS-OCT was significantly higher than those measured by the slit lamp method (328 vs. 212 μm, P < 0.001, respectively). High reproducibility was observed for each method (ICC > 0.75 for both). No statistically significant differences were found in TMH among the age groups using both SS-OCT and slit lamp methods (P = 0.985, 0.380, respectively). TMH values at both sides of the corneal center were significantly smaller than those at the corneal center (P < 0.0001).ConclusionsTMH values obtained by the slit lamp method were lower than those obtained by SS-OCT. However, both methods yielded highly reproducible TMH measurements, suggesting that they are clinically useful. Tear meniscus values did not vary by age but by measurement points in our cohort.

“…PANDO can be treated by DCR if the nasolacrimal duct is completely obstructed, and the procedure showed a relatively high anatomic success rate greater than 90% in previous studies 11. However, some patients complain of persistent epiphora despite an intact osteotomy site 12. Sung et al reported a functional success rate of 85.1% in young patients and 76.9% in older patients 3.…”

“…These rates were significantly lower than those of anatomic success. Several factors were suggested to explain these differences, including lid deformity due to aging, conjunctivochalasis,3 decreased lacrimal drainage pump function,12 and change of tear substances due to nasolacrimal duct obstructions 13. Specifically, according to Lew et al, in the tears of PANDO patients, the concentrations of calcium and inflammatory cytokines were higher than those in the tears of normal eyes 13…”

This study was designed to investigate the influence of primary nasolacrimal duct obstruction (PANDO) on the structure and function of the Meibomian gland and to examine whether it is related to functional failure after dacryocystorhinostomy surgery. Medical records of patients diagnosed as PANDO from August 2021 to February 2022 were retrospectively studied. Results of slit lamp examination, lacrimal drainage test, tear break-up time, anterior segment optical coherence tomography, and meibography were collected. Tear meniscus height, tear break-up time, meiboscore, and lipid layer thickness of tear membrane were parameters compared between the eyes with complete PANDO and the control group. Medical records of 44 patients, therefore 88 eyes were collected, and there were 28 eyes with complete PANDO (total obstruction group), while normal eyes (control group) were 30. Mean tear meniscus height was significantly higher than that of the control group (P value<0.001), but tear break-up time (P value=0.322), lipid layer thickness (P value=0.755), and meiboscore (P value=0.268) were not significantly different. However, in the cases with moderate and severe meibomian gland destruction, the lipid layer thickness of the total obstruction group was significantly thinner than the control group. Lipid secretion of meibomian glands was less in eyes with PANDO than in eyes without PANDO, under moderate to severe meibomian gland destruction. It can lead to persistent epiphora after dacryocystorhinostomy due to a compensatory response against evaporative dry eye disease. Patients should be educated before the decision to undergo surgeries about the possibilities of persistent epiphora. Further studies are needed to prove the mechanism of meibomian gland function disturbance in PANDO.
