dellen

A transient shallow depression in the cornea near the limbus which is caused by a local dehydration of the corneal stroma, leading to a compression of its lamellae. It can occur as a result of strabismus surgery, cataract surgery, swelling of the limbus (as in episcleritis or pterygium), rigid contact lens wear or senility.
