Purpose: Hansen's disease is endemic in over 140 countries worldwide and a potentially blinding condition. We describe a case of retinal vasculitis in a patient with Hansen's disease with concomitant positive antiphospholipid antibody serology, a potentially under-reported complication in this setting.
Methods: A 37-year-old Brazilian man systemically stable on triple therapy (clofazimine, rifampin, dapsone) for Hansen's disease presented for a comprehensive ophthalmic evaluation.
Results: Dilated exam revealed diffuse peripheral intraretinal hemorrhages in his right eye. Fluorescein angiography showed peripheral non-perfusion, abnormal shunt vessels and leakage from the retinal veins in the right eye and peripheral non-perfusion and vascular leakage in the fellow eye, consistent with vasculitis. Laboratory workup was notable for positive antiphospholipid antibodies (lupus anticoagulant, anticardiolipin IgM, anti-beta-2 glycoprotein 1 IgM) and normocytic anemia.
Conclusion: As antiphospholipid antibodies are present in a large proportion of patients with Hansen's disease, it is possible that retinal vasculitis may be more common than previously thought. The extent to which retinal vasculitis occurs in Hansen's disease remains uncertain and possibly underestimated due to the frequency of anterior segment scarring, which impedes retinal evaluation. Heightened surveillance for potential retinal vascular complications is warranted.
