Inflammation of the episclera, causing redness, discomfort, and sometimes mild pain in the eye.
From episclera + -itis (inflammation suffix). The medical term directly names the condition as inflammation of the episcleral tissue.
Episcleritis often appears suddenly and looks scary—the white of the eye becomes intensely red—but it usually resolves on its own in a few weeks, unlike scleritis which is far more serious.
