Zwei Fälle von schneeflockenartiger Keratitis

Abstract

Patient 1 developed snowflake-like keratitis without inflammatory response in a decompensated corneal allograft. Patient 2, who had a history of repeated corneal grafting, also developed corneal opacification which initially appeared thread-like but quickly expanded. In both patients regrafting was necessary. Histological examination of the excised corneas demonstrated dense populations of Gram-positive bacteria in the interlamellar spaces. A surrounding inflammatory reaction was lacking, which is typical for infectious crystalline keratopathy (ICK).
