ABSTRACT

Crystalline keratopathy is an important clinical entity in which crystalline deposits are noted in the cornea; it can occur secondary to a variety of causes including infections, systemic diseases and even topical medications. Infectious crystalline keratopathy (ICK), the commonest variant, is a rare, indolent corneal infection that results in greyish-white and branching stromal opacities with minimal anterior chamber or corneal inflammation. The most common risk factors for ICK include a history of penetrating keratoplasty and the associated use of topical steroids. ICK has also been reported with the use of contact lens wear and topical anaesthetic, and following lamellar keratoplasty, corneal relaxing incisions, laser in situ keratomileusis (LASIK) and cataract surgery. The stromal infiltrate cleared within two weeks and the keratopathy resolved with treatment within a month following which the topical antibiotics were stopped and steroids gradually tapered.
