CORNEAL STAINING
If only the superficial epithelial
cells are damaged, the
fluorescein staining will be
limited to the area of damage.
If the full thickness of the
epithelium is damaged
fluorescein will seep into the
stroma giving a larger area of
staining then the defect. The
borders will not be distinct
since the fluorescein is slowly
diffusing through the stroma.
