Corneal epithelial defect
Loss or disruption of the outermost layer of corneal cells, often requiring surgical intervention or protective measures.
Full Definition
A corneal epithelial defect represents a breakdown in the integrity of the corneal epithelium, the outermost cellular layer of the cornea. This condition can result from trauma, infection, dry eye disease, or surgical procedures. In ocular surgery documentation, editors must distinguish between spontaneous defects and iatrogenic ones caused during procedures. The size, location, and depth of the defect are critical parameters that influence treatment decisions and surgical planning. Proper documentation includes measurements in millimeters and anatomical location references.
Usage
Usage note: Always specify size and location when documenting epithelial defects in surgical reports.
