The Correlation Between Sleep Quality Correlates and Dry Eye Disease Symptoms in Shift Workers at Muhammadiyah University Hospital

Background: Dry eye disease (DED) is a multifactorial disorder of the ocular surface. The prevalence of DED in Southeast Asia ranges from 20% to 52.4%. In Indonesia, a study in Riau Province (2001) reported a prevalence of 27.5%. One of the risk factors for DED is poor sleep quality, which affects tear secretion and tear film stability. Shift workers are prone to poor sleep quality due to disruptions in their circadian rhythms. Objective: To analyze the relationship between sleep quality and dry eye disease symptoms among shift nurses at Muhammadiyah University Hospital (UMM). Methods: This analytical observational study employed a cross-sectional design with 80 shift nurses as respondents. Data were collected using the Pittsburgh Sleep Quality Index (PSQI) and the Ocular Surface Disease Index (OSDI). Statistical analysis was performed using Spearman’s correlation test with IBM SPSS v23. Results: The correlation analysis revealed r = 0.306 and p = 0.006 (p < 0.05), indicating a statistically significant positive correlation between sleep quality and DED symptoms. Better sleep quality was associated with fewer or milder DED symptoms. Conclusion: There is a significant relationship between sleep quality and DED symptoms among shift nurses. Improving sleep quality may be an important preventive strategy for DED.
