The authors evaluated ocular involvement in 23 patients affected by rheumatoid arthritis (RA) according to ARA criteria. Slit-lamp biomicroscopic examination showed signs of keratoconjunctivitis sicca in one patient (4%), while a positive bilateral Schirmer test was found in six subjects (26%). Fluorescein angiography, carried out in 11 of the 23 RA patients, showed retinal vasculitis in 18% of the patients examined, even if no clinical and ophthalmoscopic signs of retinal vessel inflammation were present. The authors suggest that fluorescein angiography should be performed in patients affected by particularly active RA, with recent onset of the disease (< 12 months), high titres of classical IgM rheumatoid factor and raised concentrations of circulating immune complexes. The study confirmed moreover the uncommon ocular toxicity related to the drugs frequently employed in RA treatment (antimalarials, gold salts, glucocorticoids). Indeed, only one case (4%) of posterior subcapsular cataract clearly related to steroid therapy was found.
