A corneal abrasion is a scratch to the epithelium of the cornea that is the transparent front portion of the eye. The cornea is made up of five layers and epithelium is the outermost layer of the cornea that is exposed to the environment.
This scratch may be due to multiple reasons and leads to pain and irritation. It is an eye emergency situation and any delay will cause heavy loss to your eye health. So make sure to follow the initial guidelines that we discussed in “Eye injury: Do’s and Don’ts Emergency Tips” and visit an emergency eye care center as soon as possible.

When you see an eye care professional for a corneal abrasion then he/she will perform a slit-lamp examination using fluorescein dye that is a special eye drop used by an eye care professional to identify abrasion by highlighting the surface of the cornea and then examine under the special lamp and magnification tools.
In case of extreme pain, you may receive a corneal anesthetic to temporarily reduce pain or maybe some eye drops to relax your eye muscles. The doctor also examines for any foreign particles and eye infections.
