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

Explanation:
When the cornea is injured, the outer epithelial layer can heal quickly, but if the injury penetrates into the stroma, the repairing fibers can align irregularly. This irregular regeneration forms scar tissue, which reduces corneal transparency and can blur vision. A tree twig can cause a deeper scratch, making scarring the most likely lasting consequence. Bleeding isn’t typical because the cornea has no blood vessels. Cataract formation involves the lens behind the eye, not the cornea. Fungal infection is a possible complication after plant matter trauma, but the common outcome most directly tied to the injury’s depth is corneal scarring.
