Conclusion Tear meniscus variables along with other measurements can diagnose or treat dry eye. View Ideas submitted by the community. English term or phrase: Dry eye is one of the most common ocular diseases in this cyber era. Age related changes in tear menisci imaged by optical coherence tomography. Please review our privacy policy. The contradictory relationship between TBUT and tear meniscus results could be explained by the fact that TBUT reflects stability of the tear film not the quantity of tear fluid and fluorescein use may alter the condition of the tear film.

For each patient, only measurements from the right eye were included for analysis. Tear volume decreases in normal subjects with advancing age [ 9 ]. Tempo di assottigliamento del film lacrimale pre-lenti. Acknowledgments We acknowledge Mr. Sample size was calculated by formula as 1. Showing correlations between various tear variables and OCT based tear meniscus dimensions. Published online May 1. Tear meniscus variables along with other measurements can diagnose or treat dry eye.

Italian PRO pts in category: After obtaining the formal written approval from ethical committee, the study was conducted as per declaration of Helsinki.

The three layered tear film creates a smooth ocular surface for passage of light through the eye, nourishes and provides protection from infection. Maximum patients A clinician looks at the tear film. Distribution of patients in different age groups.

This was a prospective observational case series in a tertiary care centre Himalayan Institute of Medical Sciences, Swami Rama Himalayan University, Dehradun, Uttarakhand, India over a period of six months from June to December Earliest diagnosis of dry eye require minimally invasive objective and reliable tool.

Wang and Ibrahim et al. Automatic update in Results There was significant ip in the all tear variables with the increase in the age. Review native language verification applications submitted by your peers. Please review our privacy policy. Effects of ocular surface area and blink rate on tear dynamics.

Patents, Trademarks, Copyright Law: In this prospective cross-sectional observational study, right eye of consecutive patients were studied. Open in a separate window.

For each patient, only measurements from the right eye were included for analysis. No single test can evaluate the complex tear system.

Steinert RF, Huang D, editors; pp. Blinking initiates renewal of tear film to maintain the ocular surface integrity, clear vision and comfort [ 1 ]. Hem Chander Sati for his help in statistical analysis and Mr.

Vote Promote or demote ideas. Italian PRO pts in category: Cont Lens Anterior Eye. Optical Coherence Tomography OCT employs low coherence interferometry to produce detailed cross sectional images of the anterior and posterior segment.

The tear film on the front surface of the contact lens appears to relate to contact lens comfort, but not to predict those who would remain comfortable in their contact lenses with continued wear. Return to KudoZ list. Pearson correlation test was used to correlate various tear variables with OCT based tear meniscus dimensions.

To avoid statistical complications from correlation between the right and left eyes, measurements from only the right eye of each patient were analysed. Reproducibility of tear meniscus measurement by Fourier-domain optical coherence tomography: Non-invasive break-up time assesses contact lens surface wettability, responsible for limiting the friction with the upper lid and should be recorded as part of the evaluation of lens fit.

OCT can measure the tear meniscus quantitatively in non-biased, non-invasive and non-contact methods. You can request verification for native languages by completing a simple application that takes only a couple of minutes.

This study was done to correlate the various quantitative tear variables with the tear meniscus dimensions on OCT. Patients were asked to look straight ahead at the fixating target within the OCT system.

Optical coherence tomography for measuring the tear film meniscus: The good repeatability of measurements of tear meniscus variables using OCT had been verified previously by Wang and Shen et al.

For precise and accurate measurement of tear volume, seconds are required prior to image the tear meniscus [ 13 ]. Close and don’t show again Close.

Patents, Trademarks, Copyright Law: English term or phrase: Automatic update in Tear menisci examination may be helpful in diagnosis of dry eye, as they decrease in dry eye. The balance of the system is affected by components such as tear secretion, spreading, evaporation and drainage [ 2 ].

Blinking and the mechanics of the lacrimal drainage system. Kinetic analysis of tear interference images in aqueous lzcrimale deficiency dry eye before and after punctal occlusion. The contradictory relationship between TBUT and tear meniscus results could be explained by the fact that TBUT reflects stability of the tear film not the quantity of tear fluid and fluorescein use may alter the condition of the tear film.
