Association between dry eye disease subtypes and rheumatoid arthritis

Abstract

Aim of the work

To evaluate the association of dry eye disease (DED) subtypes (aqueous deficient dry eye, ADDE and evaporative dry eye, EDE) and the presence of rheumatoid arthritis (RA) in patients.

Patients and methods

260 volunteer DED participants were recruited for an observational cross-sectional study based on the Tear Film Ocular Society Dry Eye Workshop II criteria, which included tear film osmolarity, fluorescence break-up time, and ocular surface damage assessment. Participants were recruited using QR linked to designated mobile forms to obtain symptomatology status, demographics, and RA diagnosis by their medical doctor. Tear meniscus and lipid layer were also evaluated to differentiate between ADDE, EDE, or mixed dry eye in addition to the DED diagnostic criteria. Participants with mixed dry eye were excluded from the analysis to avoid bias.

Results

After initial recruitment, 149 eligible participants with an ADDE or EDE diagnosis were included in the final analysis, where 12,1% have an RA diagnosis. The ADDE group had a higher likelihood of having RA (OR = 4.69, 95 %CI = 1.46–15.01) than the EDE group. Additionally, the number of participants with RA in the ADDE group was statistically higher than those in the EDE group (all p = 0.006). Furthermore, a correlation was obtained between RA and a diagnosis of ADDE (p = 0.005).

Conclusion

There was a significant association between ADDE and the presence of RA in patients and the association was more likely compared to those with EDE. This finding underscores the need for specific diagnostic and management strategies for RA patients presenting with DED.
