In brief: Surface vs infection
Usually a corneal abrasion is just a scrape on the surface layer of the cornea.
These tend to heal and are self limited depending on size. A corneal ulcer is secondary to inflammation or infection and causes thinning and destruction of the corneal tissue. An ulcer is more serious and potentially vision threatening.
