Band-shaped opacity of the cornea is a rare disease, first described by Dixon,1 in his textbook on diseases of the eye in 1848, as a "curious form of opacity depending upon the spontaneous deposit of earthy salts between the epithelium and the anterior surface of the cornea." Dixon therefore named this condition "calcareous film of the cornea."
Since Dixon's report, the literature has added little to the knowledge of this condition. However, as more cases were recognized it became apparent that this disease is of several types.2 By far the most common type is seen in old people, usually with sightless, degenerated and often shrunken eyes, the result of long-standing iridocyclitis due to any of a number of causes, including glaucoma and sympathetic ophthalmia. Occasionally it occurs in an elderly person with otherwise normal eyes. The pathogenesis of this type is probably a degenerative process associated with advancing
