What is a likely consequence of a corneal abrasion caused by a tree twig?

A corneal abrasion caused by a tree twig can lead to several complications, with corneal scarring being one of the most likely consequences. Corneal abrasions result in damage to the epithelial layer of the cornea, and if the abrasion is deep or not treated properly, it can lead to inflammation and the development of scar tissue as the cornea heals. This scar tissue may interfere with vision, depending on its location and extent.

While bleeding can occur in various eye injuries, it is not typical with a corneal abrasion since the cornea is avascular (lacking blood vessels). A fungal infection is less likely to arise directly from a simple abrasion unless there are specific conditions that facilitate infection or if there are organic materials involved, which may not be directly associated with a twig. Cataract formation primarily occurs due to factors such as aging or trauma to the lens, not directly as a result of a corneal abrasion. Therefore, corneal scarring is the most relevant and likely consequence of the injury caused by a tree twig in this scenario.
