Optimal cutoff value of the dry eye-related quality-of-life score for diagnosing dry eye disease.

ABSTRACT: This retrospective study aimed to determine the optimal cutoff values of the Dry Eye-Related Quality-of-Life Score (DEQS) questionnaire for diagnosing dry eye disease (DED) and classifying DED severities. Participants completed the DEQS questionnaire, the Japanese version of the Ocular Surface Disease Index (J-OSDI) questionnaire, and DED examinations. DED was diagnosed according to the 2016 Asia Dry Eye Society diagnostic criteria based on DED symptoms (J-OSDI ≥ 13 points) and tear film breakup time ≤ 5 s. Receiver operating characteristic (ROC) analysis was used to calculate the optimal cutoff values of the DEQS summary score for detecting DED and grading its severity. Among 427 patients, 296 (69.3%) and 131 (30.7%) were diagnosed with DED and non-DED, respectively. ROC analysis determined an optimal cutoff value of 15.0 points for DED diagnosis, with 83.5% sensitivity, 87.0% specificity, and an area under the curve of 0.915. The positive and negative predictive values for DEQS ≥ 15.0 points were 93.6% and 69.9%, respectively. DEQS cutoff values of 15.0, 20.0, and 26.8 points could be accepted for severity classification of DED subjective symptoms in clinical use and represent mild, moderate, and severe DED, respectively. Conclusively, the optimal cutoff values of DEQS enable DED detection and subjective symptom severity classification.

Project description:BackgroundThis study aimed to develop a Thai version of the Dry Eye-Related Quality-of-Life Score (DEQS-Th) questionnaire and evaluate its validity, reliability, and feasibility among Thai participants.MethodsThe DEQS-Th, a 15-item self-report measuring dry eye and its impact on quality of life (QOL) was developed based on the DEQS. The questionnaire was divided into two subscales: Bothersome Ocular Symptoms (six questions), and Impact on Daily Life (nine questions). It employed a 5-point Likert scale, addressing on both the frequency and the degree of symptoms. Backward and forward and cultural adaptation process translation methods were employed. Thirty healthy participants were enrolled to evaluate the feasibility of the DEQS-Th in terms of difficulty and convenience. Reliability was assessed using internal consistency determined by Cronbach's alpha, with values > 0.7 considered acceptable. Convergent validity was determined by the correlation between DEQS-Th and overall health status. Confirmatory factor analysis was conducted for its factor structure.ResultsThe participants' mean age was 38.6 ± 12.9 years, and 23 (76.7%) were females. The mean time to complete the questionnaire was 9.3 ± 2.7 min. The Cronbach's alpha of the ocular symptoms subscale, impact on QOL subscale, and summary score on frequency and degree were 0.80 and 0.70, 0.89 and 0.89, and 0.90 and 0.89, respectively. The overall health status significantly correlated with the summary score (r = 0.564, p = .001), subscale ocular symptoms (r = 0.594, p = .001), and impact on QOL scores (r = 0.626, p < .001) of the DEQS-Th, respectively. A one-factor model fitted the data the best for both the ocular symptoms subscale (CFI = 1.000, TLI = 1.000, RMSEA = 0.000) and the impact on QOL subscale (CFI = 0.998, TLI = 0.997, RMSEA = 0.053).ConclusionWhen tested among normal participants, the DEQS-Th is a valid and reliable measurement for dry eye symptoms and impact on QOL.

Project description:PurposeTo ascertain the presence of Dry Eye Syndrome (DES) in patients being treated for glaucoma, using subjective and objective methods and to examine DES impact on their quality of life (QOL).MethodA cross-sectional study was conducted by employing 156 glaucoma patients recruited from treatment centers in the Cape Coast Metropolis in Ghana. All the participants underwent dry eye examination and completed the 25-item National Eye Institute Visual Function Questionnaire (NEI-VFQ), the Dry Eye-related Quality of Life Score (DEQS) and the Ocular Surface Disease Index (OSDI). Comparisons of the clinical tests, NEI VFQ-25 subscale item and composite scores and scores of DEQS and OSDI were made among subgroups divided according to the presence of dry eye symptoms or signs. Multivariate logistic regression analysis was performed to investigate the factors that influence DES related-QOL among the patients.ResultsThe study involved 156 subjects with a mean age of 47.88 ± 16.0 years and made up of 81 (51.9%) females and 75 (48.1%) males. A One-Way ANOVA was conducted, and the F-statistic (F) indicated that there was a significant difference in the mean scores of the groups. There were significantly lower Tear break-up time (TBUT) values found in the group with definite dry compared with the group without DES and the group that was symptomatic with no signs DES in both eyes, [(F(3,151) = 13.703, p<0.001 (RE): (F(3,152) = 18.992, p<0.001 (LE)]. Similar results were found for Schirmer test (ST) [(F (3,151) = 28.895, p<0.001 (RE): (F (3,152) = 17.410, p<0.001 (LE)]. There was statistically significant difference in the mean composite score (64.93 ± 20.27) for the NEI VFQ-25 and sub-scale score of ocular pain, which was significantly lower in the group with definite dry as compared to other sub-groups (F(3,152) = 4.559, p = 0.004). OSDI scores of the group with definite dry eye (47.69-19.17) and the group that was symptomatic but with no signs (38.90-22.44) were significantly higher than those without dry eye and those that were asymptomatic but had a sign (F(3,152) = 17.896, p<0.001), with a similar trend occurring in the groups with relation to DEQS scores (F(3,152) = 8.775, p<0.001). There was a strong correlation between the DEQS and the OSDI questionnaires, and a weak correlation between the DEQS and the NEI VFQ-25 questionnaire after adjusting for all other factors (all p < 0.01).ConclusionThe study established a high presence of DES and consequently low DES related-QOL in glaucoma patients. Dry eye questionnaires are able to discriminate those who have definite dry eye from the other groups, showing its appropriateness for clinical use in glaucoma patients. Ocular surface evaluation should be conducted among glaucoma patients on topical anti-glaucoma therapy to ensure the timely detection and treatment of signs and symptoms of DES and improvement of dry-eye related QOL.
