Ocular vasculitis.

Systemic vasculitis can affect practically any structure in or around the eye. Although the ocular presentations of vasculitic disease are highly variable and may be quite subtle, it is important for physicians to understand some of the basic concepts, critical findings, and potential significance of ocular signs and symptoms. In addition to preserving sight, awareness of specific ocular syndromes may afford a critical clue to undiagnosed or newly active systemic vasculitis. A brief discussion of the most common ocular syndromes seen in systemic vascular disease is presented, with special attention given to the signs that may be appreciated by non-ophthalmologists. Recent concepts of ocular immunologic therapy are also reviewed, especially as they relate to the use of systemic immunomodulating drugs, because care of these patients often requires close cooperation between ophthalmologists, primary care physicians, and rheumatologists.
