Tear meniscus level as an indicator of nasolacrimal obstruction

Clinical assessment of the lower tear meniscus height

“…Although differences in the mean value of the TMH have been reported in normal eyes, the measurement of TMH has been found to be useful in differentiating between normal, dry eye, and nasolacrimal duct obstruction subjects (Burkat and Lucarelli, 2005; Francis et al. , 2005).…”

“…Although differences in the mean value of the TMH have been reported in normal eyes, the measurement of TMH has been found to be useful in differentiating between normal, dry eye, and nasolacrimal duct obstruction subjects (Burkat and Lucarelli, 2005;Francis et al, 2005). Furthermore, TMH measurements have shown promising results in evaluating the efficacy of punctal occlusion in subjects with different forms of dry eye (Farrell et al, 2003).…”

Change in quality of life of patients undergoing silicone stent intubation for nasolacrimal duct stenosis combined with dry eye syndrome

“…In this study, the TMH value was 0.30 mm before SI and 0.25 mm 6 months after SI. Previous studies have reported that TMH values in normal eyes vary between 0.19 and 0.25 mm, whereas those in eyes with NLD stenosis vary between 0.60 and 0.63 mm 19 21…”

“…The TMH measurement is useful to identify a disorder of the lacrimal drainage system and to postoperatively assess a nasolacrimal duct disorder 19 20. Various techniques (eg, slit lamp, optical coherence tomography and videomeniscometry) have been applied to accurately measure TMH.…”

Evaluation of impact of computer usage on various tear parameters in normal healthy tertiary hospital based population in Uttarakhand, India

“…16 The tear meniscus keep on changing from time to time and is affected by many factors like tear secretion, lid length, location of the punctum and the grey line that limits the anterior extension of tears on lid margin, palpebral aperture and lacrimal drainage. [17][18][19] On OCT tear meniscus studies, TMH among computer users was 236 μm which was significantly low as compared to nonusers which was not in accordance to Bagheban et al (Table 3). 11 In the present study the tear variables were measured by OCT from the lower tear meniscus because it act as a good predictor of dry eye and had improved sensitivity and specificity as compared to the superior meniscus as concluded by Shen et al Quantification of the upper meniscus has been limited by several factors, including eyelashes that block the view of the tear meniscus, rapid movement and twitches of the upper eyelid and smaller meniscus volumes as compared with the lower meniscus.…”
