The full form of PEE can be Punctate Epithelial Erosions.
Punctate Epithelial Erosions (PEE) Explained
PEE refers to a condition related to ocular surface dryness. Let's break this down:
-
Definition: PEE indicates areas where epithelial cells (the surface cells of the cornea) have been lost.
-
Detection: These erosions can be identified using fluorescein dye, which stains the areas where the epithelial cells are missing. As the reference text states, "Punctate epithelial erosions (PEE) are evidence of ocular surface dryness. They represent areas of epithelial cell loss and therefore stain positively with fluorescein."
-
Significance: The pattern and location of PEE can help determine the underlying cause of the dryness.
