corneal infiltrates

corneal infiltrates 

Small hazy greyish areas (local or diffuse) composed of inflammatory cells, proteins, etc. surrounded by oedema and located in the cornea typically near the limbus. The adjacent conjunctiva is usually hyperaemic. They appear as a result of corneal inflammation (e.g. marginal keratitis, microbial keratitis), reaction to solution preservatives and some contact lens wear (especially extended wear) which causes prolonged hypoxia. Management depends on the cause; for example, if due to contact lenses, cessation of wear is usually indicated, otherwise drug therapy is required. See acanthamoeba keratitis; superior limbic keratoconjunctivitis.
