AN 83-YEAR-OLD woman sought treatment for bilateral visual loss, which
had developed during the preceding week. She reported several weeks of weight
loss, headache, scalp tenderness, and jaw claudication.
The examination revealed no light perception in either eye. Both corneas
were edematous (Figure 1 and Figure 2) and the intraocular pressure by
applanation was 2 mm Hg OU. Corneal edema obscured the view of the right optic
disc; the left disc was swollen. Westergren erythrocyte sedimentation rate
was 132 mm/h.
