To determine whether quality of life (QOL) and health utility are affected to the same extent among dry eye (DE) patients with short tear film break-up time dry eye (TBUT-DE) with minimal clinical signs were as severe as aqueous-deficient dry eye (ADDE). A multicenter cross-sectional study was conducted among DE patients who visited one of 10 eye clinics in Japan. Among the 463 registered patients, this study involved 449 patients with DE who were aged 20 years or older. Ophthalmic examination findings were assessed, including tear film break-up time (TBUT), Schirmer I value, and keratoconjunctival staining score. QOL was evaluated with the Dry Eye-Related Quality-of-Life Score (DEQS; 0 [best], 100 [worst]) and health utility (1 [total health], 0 [worst]) with the Health Utilities Index Mark 3 (HUI-3); scores were stratified by DE subgroup. Median (interquartile range) of DEQS and HUI-3 scores across all participants were 21.7 (10.0–40.0) and 0.82 (0.69–0.91), respectively. Median (interquartile range) DEQS and HUI-3 scores in the ADDE group were 23.3 (10.0–40.0) and 0.79 (0.69–0.88), respectively; those in the short TBUT-DE group were 23.3 (13.3–38.3) and 0.82 (0.74–0.92), respectively. There were no significant between-group differences in questionnaire scores. Among the ophthalmic examination findings, a weak significant correlation between TBUT, corneal staining score and keratoconjunctival staining score to DEQS; TBUT and Schirmer test values to HUI-3, were seen. The burden of short TBUT-DE on QOL as assessed by the DEQS and HUI-3 was as severe as that in ADDE. Our findings suggest that clinicians should be aware of the impact of short TBUT-DE on patients QOL and utility values. University Hospital Medical Information Network (registration no.

We investigated the association between dry eye disease and systemic comorbidities, including dry eye subtype, quality of life (QOL) and health utility among patients with dry eye disease. This cross-sectional, observational study enrolled 449 patients with dry eye disease (386 females; mean age, 62.6 ± 15.7 [range, 21–90] years). Ophthalmic examination findings included tear film break-up time (TBUT), Schirmer I value and keratoconjunctival staining score. QOL and health utility were evaluated using the Dry Eye-Related Quality-of-Life Score (DEQS) and Human Utility Index Mark 3 (HUI-3), respectively. Background information, including systemic comorbidities, was obtained. Prevalence of systemic comorbidities was 48.8% (219/449). No significant difference occurred between DEQS and systemic comorbidity. However, patients with dry eye disease and systemic comorbidities (depression and insomnia) exhibited significantly worse ocular surface parameters, particularly regarding TBUT, than those without. Dry eye disease with insomnia or depression comorbidity significantly correlated with friction-related diseases (including conjunctivochalasis or lid wiper epitheliopathy). A high prevalence of several systemic comorbidities occurred in patients with dry eye disease. This study shows an association between ocular signs and systemic comorbidities, particularly depression and insomnia. Ophthalmologists should be aware of patients’ systemic comorbidities in the diagnosis and management of dry eye disease.

To assess the efficacy of bandage contact lens (BCL) application to promote epithelialization and alleviate pain following corneal transplantation. Twenty-six consecutive patients who underwent corneal transplantation were randomly assigned to undergo BCL application (BCL group, n = 14) or no BCL application (control group, n = 12) at the end of the surgery. Corneal epithelialization was analyzed by photography using fluorescein staining, and ocular pain was measured using a visual analog scale. The mean size of the epithelial defect relative to the graft area in the BCL group was 21.80 ± 35.10 % at the end of surgery, 18.20 ± 31.10 % on postoperative day 1, and 5.45 ± 11.10 % on postoperative days 3 to 5. These values in the control group were 9.64 ± 17.60 % at the end of surgery, 11.50 ± 25.70 % on postoperative day 1, and 0.00 ± 0.00 % on postoperative days 3 to 5. There were no significant differences in the speed of epithelialization between the two groups. The mean preoperative pain score in the BCL group was slightly higher than that control (4.27 ± 1.96 vs. 2.41 ± 2.18, respectively; P = 0.039). The scores significantly increased on postoperative day 1 and promptly returned to preoperative levels by day 7 in both groups, and there were no significant differences between the groups. No significant benefits of BCL application at the time of corneal transplantation were observed in this study. The efficacy and safety of BCLs in eyes with compromised epithelialization require further study. UMIN 000019091 . Date of registration: 2015/09/22
