P109 Ocular manifestation of rheumatoid arthritis

Abstract

Abstract Background/Aims Ocular manifestation associated with rheumatoid arthritis (RA) is common and should be systematically investigated by an ophthalmological examination. It may precede or complicate the disease. It manifests as a dry-eye syndrome in 38% to 45% of cases, scleritis in 0.2 to 6.3% of cases, episcleritis in 0.17 to 3.7% of cases, and peripheral ulcerative keratitis in 3% of cases. The aim of this study was to describe ocular involvement in RA and to identify factors predictive of its occurrence. Methods This is a retrospective study of patients with RA defined according to the ACR- EULAR 2010 criteria, followed up in the internal medicine department between 2015 and 2022. Patients were divided into two groups: G0 including patients without ocular involvement and G1 including patients with ocular involvement. Results Eighty patients were diagnosed, 65 women and 15 men, giving a sex ratio (F/H) of 4.33. The mean age was 60.79 years [extremes: 30-90 years]. The mean age of disease onset was 46.34 years [extremes: 22-82 years]. Among our 80 patients, 20 had RA-related ocular involvement (25%). These included 18 women and two men. Ocular involvement consisted of dry-eye syndrome (17 cases), superficial punctate keratitis (4 cases), corneal perforation (one case), and unilateral diffuse scleritis (one case). The ocular examination had also revealed corticosteroid adverse effects: corticosteroid-induced cataract (four cases) and corticosteroid-induced glaucoma (three cases). Sjogren’s syndrome associated with RA was present in 76.47% of cases. There was no difference between the two groups in terms of age (62.25 vs. 44.22 years, p = 0.943), age of disease onset (47, 23 years vs. 44.22 years, p = 0.569), rheumatoid factor level (335.29 IU/L vs. 329.15 IU/L, p = 0.393) and anti-CCP antibody level (225.08 IU/L vs. 119.23 IU/L, p = 0.070). CRP was significantly higher in patients with no ocular involvement (225.08 mg/l vs. 118.23 mg/l, p = 0.007). erosive character was observed more in G0 than in G1, but without any significant difference, respectively 85.29% vs. 68.42%; p = 0.146. Conclusion According to our study, a quarter of patients followed for RA had ocular manifestations dominated mainly by dry syndrome. However, no predictive risk factor was found for this condition, be it clinical, immunological, or radiological. Disclosure I. Fenniche: None. Z. Aydi: None. M. Somai: None. F. Daoud: None. B.
