Corneal Degeneration 5621 Calcific Band Keratopathy

After many years of chronic inflammation of the anterior chamber (chronic uveitis and keratitis) with shrinkage of the eyeball or in patients withjuvenile polyarthritis, calcific deposits occur in Bowman's layer, causing a transverse zone of opacification in the region of the palpebral fissure. The limbus region will remain clear (Fig. 5.15). This change significantly impairs vision. The opacification can be completely removed and vision restored by chelat-ing the calcifications with a sodium EDTA solution.
