Fluorescein staining is a routine procedure for determining the health of the corneal surface. In areas where the surface covering has been lost, the dye is able to seep into the deeper layer of the cornea, revealing the injury as a bright green spot.
Reasons to UseRelated Observations
A quick, inexpensive test for determination of surface breaks in the corneal surface. The dye also collects in the nostril, demonstrating that the naso-lacrimal (tear) duct is clear.
