Corneal epithelial defect: Corneal epithelial damage can range from mild diffuse punctate epithelial keratitis (PEK) to a complete epithelial defect. A complete epithelial defect may not take up fluorescein dye as rapidly as in a routine corneal abrasion; therefore, it may be missed. If an epithelial defect is suspected but not found on the initial evaluation, the eye should be reexamined after several minutes. The size of the defect should be recorded so as to document response to treatment on subsequent visits.
