AB Objective: To evaluate the accuracy of diagnosing dry eye disease (DED) by using theVisionix VX120+, to establish reference values for tear meniscus height (TMH) and non-invasivebreak-up time (NIBUT), and to compare the NIBUT measurements with the fluorescein tear break-uptime (FBUT), Methods: fifty-eight subjects (34 dry eye and 24 control) were enrolled. The TMH, firstNIBUT, and NIBUT50% were evaluated with the Visionix VX120+, and the FBUT was measured witha slit-lamp. The Receiver Operating Characteristic (ROC) curve was used to evaluate the diagnosticperformance, and the Bland–Altman method was performed to analyze the agreement. Results: Theareas under the curve were 0.62, 0.60, and 0.70 for the TMH, first NIBUT, and NIBUT50%, respectively.The optimal cut-off values (sensitivity, specificity) were 0.29 (0.62, 0.67), 5.05 (0.85, 0.46), and 7.35(0.65, 0.79) for the TMH, first NIBUT, and NIBUT50%, respectively. The mean differences (lower,upper limits of agreement) were −1.10 (−8.78, 6.58) and 1.55 (−5.68, 8.78) for the first NIBUT vs.FBUT and the NIBUT50% vs. FBUT, respectively. Conclusions: In conclusion, the NIBUT50% canbe a useful tool for dry eye screening, with acceptable values of sensitivity and specificity. First, theNIBUT and NIBUT50% should not be used interchangeably with the FBUT.
