Evaluating the diagnostic utility of evaporative dry eye disease markers

Abstract

their diagnosis was revised when systemic symptoms persisted despite corticosteroid therapy. In our experience GCA is an extremely rare cause of scleritis. Patients with scleritis in combination with cephalic symptoms suggestive of GCA, should arouse suspicion of alternate vasculitides. The crossover between symptoms, laboratory results and histopathology can make this a difficult distinction. Thorough systemic review and ongoing monitoring is necessary even after commencement of corticosteroid therapy; hence, referral to rheumatology and immunology is recommended. Early immunosuppressive therapy is often more pressing in systemic vasculitides other than GCA, and can significantly impact on the patient's prognosis.
