Wegener's Granulomatosis and Corneo-Scleral Ulcer

To the Editor:— Wegener's granulomatosis is a rare collagen disease of unknown etiology originally described by Klinge. 1 Wegener 2 was the first to correlate the findings into a specific entity distinct from periartertis nodosa. Since then little has been added to basic knowledge of the etiology or pathogenesis of this disease. The usual clinical picture has been well outlined by Fahey. 3 There is no predisposition for either sex. Age varies greatly, but is usually in the third to fifth decade. The onset is heralded by upper-respiratory-tract symptoms, most often nasal stuffiness and sinusitis.
