Answer: C) S.aureus
Explanation: The image shows a staphylococcal marginal infiltrate, which is thought to be caused by a hypersensitivity to staphylococcal exotoxins. The subepithelial infiltrate typically has a lucent area separating it from the limbus. The epithelium overlying the infiltrate may break down, causing many of the patient’s symptoms. Patients commonly have blepharitis and meibomitis, although blepharitis can be noticeably absent. Mild steroid drops (prednisolone 0.125%) effect quick resolution. A combination antibiotic and steroid drop is often an excellent choice. Slight corneal thinning and vascularization may be the only remnants of a previous episode.
