Background and objective: Rheumatoid arthritis is a systemic inflammatory disease. Ocular manifestations involved with rheumatoid arthritis are keratoconjunctivitis sicca, episcleritis, scleritis, anterior and posterior uveitis, dry eyes and ulcerative keratitis. This study aimed to detect the prevalence of ocular manifestations in rheumatoid arthritis patients, find out the relation between the effects of disease modifying anti-rheumatic drugs, biological agents and ocular complications in rheumatoid arthritis patients and explore role of anti-cyclic citrullinated peptide antibodies. Methods: This is a cross-sectional clinical study of 60 rheumatoid arthritis patients who have attended Rizgary Teaching Hospital in Erbil. A data information about symptoms of ocular manifestations and history of ocular complications before starting disease modifying anti-rheumatic drugs and/or biological agents were taken. Musculoskeletal examination, serum Anti-CCP antibodies test were done. Ocular examination by ophthalmologist was done. Results: This study was conducted from April to November 2015 and involved 60 patients; 55 females and five males with a mean± SD age of 46 ± 11.46 years. Thirty nine (65%) patients had ocular manifestations of rheumatoid arthritis. The most frequent manifestation was dry eyes 30 (50.0%). There was no relation between severity of the rheumatoid arthritis disease and ocular manifestation (P = 0.529). There was a relationship between the Anti-CCP antibodies titer and presence of ocular manifestations in rheumatoid arthritis patients (P = 0.006). There were no curable effects of the disease modifying anti-rheumatic drugs, biological agents on ocular manifestations in rheumatoid arthritis patients (P = 0.787). Conclusion: Dry eye was the most common ocular manifestation, anti-CCP antibodies are a sensitive marker for ocular manifestations. Disease modifying anti-rheumatic drugs and biological therapies provide no significant efficacy in treatment or prevent the occurrence of ocular manifestations in rheumatoid arthritis patients.
Rheumatoid arthritis (RA) is a systemic inflammatory disease associated with a number of extra-articular organ manifestations. Ocular manifestations involved with RA are keratoconjunctivitis sicca, episcleritis, scleritis , corneal changes, and retinal vasculitus. The etiopathogenesis of this autoimmune disorder is still unknown. Aim of our study was to present different ocular manifestations of RA and their frequency. We have examined 691 patient with the diagnoses of RA. All examined patients were in I or II stage of the disease according to criteria of The American College of Rheumatology. Ophthalmological exam obtained: visual acuity by Snellen sings, biomicroscopy of anterior segment, Schirmer test, tear break-up time (BUT), applanation tonometry and indirect ophthalmoscopy. In all patients with retinal vasculitis fotofundus and in indicated cases fluorescein angiography was preformed. The most common manifestation of ocular involvement was keratoconjunctivitis sicca. Episcleritis was diagnosed in 5.06% patients with RA, while scleritis was present in 2.06% of patients. Diffuse scleritis was present in one patient, while nodular was present in 13 patients. There were no patients with posterior or necrotizing scleritis among examined patients. Sclerosing keratitis was diagnosed in 11 female patients. It is characterized with peripheral thickening and opacification of the stroma adjacent to the site of inflammation. Posterior scleritis or scleromalacia of cornea was not present in our patients, because all of them were in I or II stage of disease. Retinal vasculitis was present in three patients, two male and one female patient (0.45%). Ocular manifestation was present in 27.2% of patients. Women were more affected.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
