I know that corneal abrasions on the corneas can be bad, but can you predict which ones will go bad?

Corneal abrasion: The deeper the abrasion the greater the scarring. If it is related to herpes virus the scaring is even worse. Zoster, shingles, can cause scarring in a significant number of people as well.

It depends.: Depends on the cause of the corneal abrasion. If it is due to an accidental superficial scratch from a finger nail or piece of paper, these usually heal quickly and leave no long term visual effects. If it is due to an infectious etiology such as a bacterial corneal ulcer or viral herpes, the corneal defect is likely deeper and associated with other corneal findings. These require topical therapy.

Infection: Any corneal abrasion that becomes infected prior to healing of the epithelium may cause serious damage to the eye: scarring, perforation.
