A 76-year-old woman hospitalized for treatment of an inferior vena cav
a thrombus was noted to have eosinophilia as well as asthma, periphera
l neuropathy, jaw claudication and visual loss. Pathological review of
a temporal artery biopsy revealed vasculitis with eosinophils but no
giant cells. Treatment with high dose corticosteroids resulted in impr
ovement of visual acuity from hand motion to 20/60. Whereas at least 6
cases of temporal artery involvement with Churg-Strauss syndrome have
been reported, visual loss has occurred in only 3 patients. In each o
f these cases, visual loss was permanent.
