Understanding Bright Green Staining After Corneal Abrasion: Fluorescein Staining Explained

The procedure you are referring to is called fluorescein staining. Fluorescein staining is a diagnostic test used to detect damage to the cornea, the clear outer layer of the eye. Fluorescein is a dye that, when applied to the eye, will temporarily stain any areas of the cornea that are damaged or abraded. This staining allows the doctor to better visualize and assess the extent of the damage.

Fluorescein staining is typically performed in the doctor's office and takes only a few minutes. The doctor will first apply a drop of fluorescein to the eye and then ask you to blink several times. The fluorescein will spread over the surface of the eye and any damaged areas will be stained bright green. The doctor will then use a special light to examine the eye and look for any green staining.

Fluorescein staining is a safe and painless procedure and is an important tool for diagnosing corneal abrasions and other eye injuries.
