Abstract
Purpose :
To evaluate sleep disorders in patients with dry eye disease (DED) and allied irritating ocular diseases.
Methods :
This is a cross-sectional and case-control study and seven hundred and fifteen outpatients diagnosed with DED, chronic conjunctivitis, or allergic conjunctivitis across six eye clinics were initially enrolled. Of these, 301 patients with DED and 202 age-matched control participants with other ocular surface diseases were analyzed. The Pittsburgh Sleep Quality Index (PSQI) and Hospital Anxiety and Depression Scale (HADS) were evaluated.
Results :
The mean PSQI and HADS scores were 6.4 ± 3.2 and 11.1 ± 5.7 for severe DED (n = 146), 5.5 ± 3.3 and 9.8 ± 4.0 for mild DED (n = 155), 5.5 ± 3.1 and 9.5 ± 6.6 for chronic conjunctivitis (n = 124), and 5.0 ± 3.3 and 8.9 ± 5.3 for allergic conjunctivitis (n = 78). There were significant differences among these diagnostic groups for PSQI (P < 0.05). Regression analysis of patients with DED revealed the PSQI and HADS scores were significantly correlated with the severity of DED (P < 0.05).
Conclusions :
Sleep quality in patients with DED was significantly worse than in patients with other irritating ocular surface diseases and it was correlated with the severity of DED. The present results suggest the quality of life in patients with DED may be exacerbated by sleep disorders. Psychiatric treatment focusing on sleep disorders could therefore beneficial for these patients.
