Acute corneal calcification.

: This case report describes acute unilateral calcium deposition in the central cornea of a uremic patient with corneal exposure. A mechanism of calcium deposition is discussed. It is suggested that a high calcium-phosphorus product, combined with local factors secondary to injury of the exposed corneal epithelial cells, helped to trigger rapid and dense calcification. Details of the removal technique are presented. Constant irrigation of freshly prepared chelating agent combined with vigorous and frequent massage of residual deposits is necessary to completely remove dense concentrations of calcium.
