Abstract

The oomycete Pythium and the protozoan Acanthamoeba can cause fulminant and recalcitrant keratitis, respectively. These infections are not only sight-threatening but can also threaten the structural integrity of the eye. A high index of suspicion is required to identify Pythium keratitis given its uncommon occurrence. Acanthamoeba keratitis is most commonly associated with contact lens wear. However, its coexistence with Pythium has not been reported. We present the successful management of a case of contact lens-related keratitis, coinfected with Pythium and Acanthamoeba.
