건성안 진단에서 눈물띠 측정 스트립의 유효성

Abstract

Purpose: To evaluate the efficacy of strip meniscometry test for dye eye syndrome (DES) by measuring the correlation between strip meniscometry and conventional test measurements. Methods: All subjects were examined using the Schirmer test, tear breakup time (TBUT) and strip meniscometry using SMTube (Echo Electricity Co., Ltd., Fukushima, Japan). Tear meniscus height (TMH), tear meniscus depth (TMD) and tear meniscus area (TMA) were measured using Fourier-domain optical coherence tomography. The DES group (n = 46 eyes) was compared with the normal group (n = 30 eyes) and correlation was assessed using Spearman’s correlation coefficient. Results: Strip meniscometry measurement was significantly correlated with Schirmer score (r = 0.6080, p < 0.01), TBUT (r = 0.5980, p < 0.01), TMH (r = 0.6210, p < 0.01), TMD (r = 0.6080, p < 0.01) and TMA (r = 0.6370, p < 0.01). Strip meniscometry was significantly lower in the DES group (4.58 ± 1.94 mm) than the normal group (7.07 ± 2.61 mm, p < 0.05). Conclusions: Strip meniscometry was significantly correlated with other conventional test measurements for dry eye syndrome. Strip meniscometry is less time consuming and a less invasive method than the Schirmer test. Strip meniscometry could be an efficient tool to evaluate patients with dry eye syndrome in a clinical setting.
