Purpose
To compare the results of NIBUT measurements provided by the new Dry Eye screening module of the VX120+ platform with those obtained with the standard procedures in subjects with and without Dry Eye.
Setting
Optometry Clinic of the University of Alicante, Spain. Department of Optics, Pharmacology and Anatomy, University of Alicante, Spain.
Methods
Patients with and without Dry Eye were recruited and distributed in two groups. Dry Eye was diagnosed by the following tests: tear volume via the Schirmer test, OSDI (Ocular Surface Disease Index) questionnaire, break-up time (BUT) and corneal staining. The Dry Eye module of the Visionix VX120+ was used to assess the quantification of the time of breaking the tear surface and the measurement of the tear meniscus.
Results
30 controls (age 48.33 ± 13.33; 20 female) and 17 cases with Dry Eye (50.18 ± 10.14; 12 female) were enrolled. The non-invasive break-up time (NIBUT) measured with the VX120+ in control subjects provided significantly lower values than with the traditional examination (VX120+ 5.6 ± 4.08s vs. slit lamp 7.67 ± 4.63s; p=0.004), although no differences were found in the Dry Eye cases (VX120+ 5.27 ± 4.65s vs. slit lamp 4.83 ± 2.27s; p=0.717). The range of agreement between both methods was [-5.14; 9.28 s] in controls and [-0.78; 8.40 s] in cases. A total of 14 (82.35%) cases were detected in the case group as having a low NIBUT (<6s) via the VX120+, while 12 (70.59%) were detected via slit lamp examination.
Conclusions
The Visionix VX120+ can be used as an screening tool for Dry Eye, as it can consistently detect Dry Eye cases that present a low NIBUT. The limits of agreement were narrower in patients with Dry Eye than in control subjects.
