The Relationship Between Anxiety Sensitivity, Emotional States, and Dry Eye Disease Symptom Severity: A Cross-Sectional Study.

Dry eye disease (DED) is often comorbid with psychiatric conditions and psychological disturbances like anxiety and depression. The psychological symptoms are mostly considered to be a consequence of DED or a side-effect of medication. However, the possible psychological etiology of DED is seldom explored. This study explores the relationship between anxiety sensitivity (AS), unpleasant emotional states, and the severity of DED symptoms in a healthy general population sample in Croatia. A total of 766 adults (62.27% females) aged between 18 and 88 years completed an online survey consisting of the Ocular Surface Disease Index (OSDI), Anxiety Sensitivity Index (ASI), and Depression Anxiety Stress Scales (DASS21) together with socio-demographic data. The results revealed significant positive correlations between ASI, emotional states, and OSDI (r = 0.25-0.29, < 0.01). Mediation analysis showed that DASS21 significantly mediates the relationship between ASI and OSDI (B = 0.1, CI = [0.004, 0.2]). Highly anxiety sensitive people are more sensitive to DED symptoms, which additionally increases in a state of emotional stress. Thus, DED symptoms are perceived more intensely and frequently than in less sensitive people. Understanding these associations is crucial for comprehensive DED management, indicating potential benefits from addressing psychological health in DED patients and eye health in psychiatric patients.
