The aim of this study was to find the correlation between severity of dry eye and rheumatoid arthritis (RA) disease activity. Forty- two RA patients with dry eye were recruited from Rheumatology Outpatient Clinic in Minia University Hospital. Assessment of RA disease activity was performed using disease activity score (DAS-28). Ocular tests include Schirmer test I, tear film break up time (TBUT) and ocular staining score (OSS) was performed by ophthalmologist to find evidence of ocular dryness. Erythrocyte sedimentation rate (ESR), rheumatoid factor (RF), anti SSA/Ro and anti SSB/La was also tested. Patients with severe dry (OSS ≥ 3) underwent minor salivary gland biopsy (MSGB) as suspected to have secondary Sjögren's syndrome (SS). Of 42 RA patients, 30 had definite dry eye. DAS-28 did not show significant correlation with any of ocular tests for dryness while the duration of RA was significantly positively correlated with Schirmer test and OSS. The biopsy results of RA patients with severe dry eye show no evidence of SS. The severity of dry eye is not correlated with activity of RA but with its duration.
