A corneal abrasion is a scrape or scratch injury of the cornea.
This painful condition can be caused by a small foreign body, trauma, contact lens use, malnutrition, dry eye syndromes, and certain cancer therapies. The abrasion allows organisms to enter, leading to corneal infection. Bacterial, protozoal, and fungal infections can lead to corneal ulceration, a deeper injury.
This problem is an emergency because the cornea has no separate blood supply and infections that can permanently impair vision develop rapidly.

A corneal ulcer is a defect in the surface epithelium of the cornea that involves the underlying stoma. It is common in contact lens wearers and presents as eye pain, blurry vision, and photophobia.
