Dry Eye Disease (DED) severity correlates with insomnia. More severe dry eye symptoms and signs are linked to worse insomnia in patients, particularly nocturnal awakenings.
Area of Science:
- Ophthalmology
- Sleep Medicine
- Public Health
Background:
- Dry Eye Disease (DED) is a prevalent ocular surface condition impacting patient well-being.
- The relationship between DED and sleep quality is gaining attention, suggesting a reciprocal connection.
- Understanding this link is crucial for managing DED patients.
Purpose of the Study:
- To investigate the relationship between Dry Eye Disease and sleep quality.
- To analyze this association using both survey data and instrumental measurements.
- To assess the impact of insomnia severity on DED symptoms and signs in a large patient cohort.
Main Methods:
- A cross-sectional study involving 1182 Dry Eye Disease patients.
- Utilized Insomnia Severity Index (ISI) and Ocular Surface Disease Index (OSDI) questionnaires.
- Collected physician-assessed data on tear break-up time (TBUT) and ocular surface staining (OSS).
Main Results:
- A significant association was found between the severity of DED symptoms/signs and insomnia severity.
- Higher OSDI scores, reduced TBUT, and increased OSS correlated with worse insomnia.
- DED severity was more strongly linked to nocturnal awakenings than to difficulty falling asleep.
Conclusions:
- This study confirms a complex relationship between Dry Eye Disease and insomnia.
- In DED patients, increased insomnia severity corresponds to more severe DED symptoms and clinical signs.
- Findings highlight the importance of addressing sleep disturbances in DED management.
