Epithelial Inclusion Cyst


Occasionally, following corneal healing, epithelial cells may become trapped beneath the epithelial surface and organize into small cysts which gradually enlarge as they accumulate proteinacious debris. Clinically these lesions appear as one or more focal, relatively well-circumscribed, smooth, raised yellow to tan swellings, protruding from the corneal surface at the site of prior trauma. A mild superficial vascular response is typically associated with the presence of inclusion cysts. These lesions do not however, result in significant discomfort.
