| A rare scleritis characterized by severe ocular inflammation of sclera associated with an underlying systemic inflammatory condition, most often rheumatoid arthritis, granulomatosis with polyangiitis, but also seronegative spondyloarthropathies, vasculitides and systemic lupus erythematosus. Ocular presentation is a tender or painful, violet-blueish eye, with injection of deep scleral vessels. It can be unilateral or bilateral. Immune-mediated scleritis is more often granulomatous and/or necrotizing. Systemic clinical signs depend on the underlying disease. |
