Fluorescein staining of the cornea

Richard C. Allen, MD, PhD, FACS
Additional Notes: 00:26

Fluorescein staining of the cornea is performed by first placing a drop of sterile saline on a sterile fluorescein strip.  The fluorescein is then placed in the inferior cul de sac of the eye by pulling down on the lower lid and gently touching the bulbar conjunctiva with the fluorescein strip.  The patient blinks to distribute the dye, and the cobalt blue light is used to determine if there are any corneal epithelial defects.
