Band keratopathy is a common disorder of  the cornea characterized by an opacification of the superficial cornea within the interpalpebral fissure. Most cases are due to a deposition of calcium salts in Bowman layer and the superficial corneal stroma [calcific band keratopathy]. Others are due to a deposition of a yet to be identified protein [chronic actinic keratopathy]. Band keratopathy may be associated with a systemic disease with hypercalcemia. It is also a manifestation of renal tubular acidosis II.
