retinal vasculitis
Retinal vasculitis is defined as inflammation of the retinal vessel walls or perivascular spaces affecting veins more commonly than arterioles (except in polyarteritis nodosa, ANCA-associated vasculitis, SLE, and Susac syndrome). It occurs bilaterally in almost all cases. Can be complicated by occlusive retinal vascular disease secondary to obliterative or thrombotic processes. Can be primary or seen in conjunction with other forms of uveitis (e.g., posterior uveitis). Can be associated with systemic rheumatic disease, such as Behçet’s disease and sarcoidosis, but does not necessarily correlate well with systemic vasculitis.
