Fluorescein Staining - diagnosing corneal injury

Fluorescein Staining is a simple procedure for diagnosing CORNEAL INJURY or foreign objects in the EYE. The ophthalmologist places a strip of paper containing fluorescein at the edge of the eye. The dye rapidly leaches into the tears. Some people experience a slight burning sensation when the dye washes across the eye for the first time. Blinking disperses the tears across the CORNEA. With the regular room lights turned off, the ophthalmologist shines a cobalt blue light on the eye. Any breach in the eye’s surface shows as bright green. The tears wash the fluorescein from the eye within a few minutes.
