8. Inflammation around the eye.
Lastly, if you are suffering from keratitis, you may notice that the area around your eye is swollen or inflamed. This condition occurs when the cornea, the clear part of the eye that covers the pupil and iris, becomes inflamed, which leads to all of the other symptoms that have been noted on this list.
When the eye itself is damaged, the area surrounding it can also become inflamed and swollen. The reason? Swelling is the body’s natural way of protecting itself from an injury or illness. Since keratitis is caused by injury or infection, the swelling can extend beyond the cornea itself to the area that surrounds the eye. This swelling can be significant, and as such, you can be visible.
In addition to the swelling, the skin around the eye may look red. See a doctor if you ‘re experiencing swelling around your eye.
