Purpose: To evaluate the association of strip meniscometry tear meniscus volume measurement with signs and symptoms related to dry eye. Methods: This cross-sectional study enrolled 2234 consecutive outpatients and used dry eye symptomatology and related ocular surface examinations, including the Schirmer test, fluorescein tear film break-up time (BUT), corneal fluorescein vital staining and strip meniscometry. The strip meniscometry cut-off was estimated using a receiver operating characteristic analysis. The subjective symptoms consisted of six binarized items: dryness, fatigue, photophobia, pain, irritation, and blurring. The clinical signs were also binarized by the cut-off in each test. The presence of all signs and symptoms were then analyzed using Hayashi’s quantification theory type III analysis. Results: The mean age of the participants was 59.3 ± 17.3 years. The mean values for Schirmer test, BUT, corneal fluorescein staining, and strip meniscometry were 13.6 ± 9.6 mm, 3.1 ± 2.1 seconds, 0.40 ± 0.66, and 2.4 ± 2.7 mm, respectively. The Schirmer test was negatively correlated with age (r = –0.152; P < 0.01), whereas the BUT and strip meniscometry were not. All pairs of Schirmer test, BUT, and strip meniscometry had significant correlations, but the greatest correlation was found between BUT–strip meniscometry (r = 0.238; P < 0.01). An strip meniscometry cut-off length of 2.5 mm (area under the curve = 0.618) was calculated. Hayashi’s analysis found high similarity among the presence of signs by strip meniscometry, BUT. and corneal fluorescein staining, and three nonvisual symptoms (pain, irritation, and dryness) had a distinct similarity. Conclusions: Strip meniscometry results using the cut-off of 2.5 mm could be a useful clinical indicator for the initial screening of dry eye. Translational Relevance: This large-scale case-control study further confirmed tear strip meniscometry with the new cut-off is a useful tear function examination for dry eye; it is a 5-second noninvasive procedure and associated with clinical symptoms and corneal parameters.
