Ocular involvement in granulomatosis with polyangiitis: A single-center cohort study on 63 patients

Objective: To analyse the ocular manifestations of patients with GPA, their treatment and outcome. Methods: Retrospective cohort study performed at the National Referral Center for Vasculitis, Cochin Hospital, Paris (France), from January 2005 to December 2015. Among 308 patients with a new diagnosis of GPA in accordance with the American College of Rheumatology classification criteria and/or revised Chapel Hill nomenclature definitions, we identified those with ocular involvement and a subsequent follow up in our center. Results: The prevalence of ocular involvement in our GPA series was 38.6%; 63 patients were analysed with a median follow-up of 50.5 months (IQR: 17.8-82.8). Scleritis (18 patients, 28.6%) and episcleritis (18 patients, 28.6%) were the most common ophthalmologic manifestations, followed by orbital disease (13 patients, 20.6%). Bilateral involvement and visual acuity loss was seen in 29.1% and 16.7% of patients, respectively. Ocular involvement was the first GPA manifestation in 9 patients (14.3%), concomitant with systemic manifestation in 36 (57.1%), and occurred only during follow-up in 18 (28.6%). The indication for GPA treatment was suggested by ocular involvement in 12 patients (19.0%), by systemic features in 40 (63.5%) and by both ocular and systemic involvement in 11 (17.5%). Remission of ocular involvement was achieved in 51 patients (80.9%). In the remaining 12 (19.1%), symptoms persisted or even worsened, finally leading to rituximab (RTX) therapy in 8 of them (66.7%). Altogether, when used as first line or for refractory disease, ocular remission was achieved in 11 of the 12 cases (91.7%) treated with RTX versus 34 of the 47 cases (72.3%) treated with CYC (P =.260). Eye disease relapsed in 14 patients (22.2%). RTX allowed achievement of remission in 8 of them (57.1%). In the remaining six, other immunosuppressive drugs were used. Conclusions: Scleritis and episcleritis are the most common ocular manifestations in GPA, most of the time associated with other systemic manifestations. In > 40% of cases, ocular manifestations were refractory to initial treatment or recurrent and led to RTX prescription, which appeared to be useful in these situations.
