Retinal detachment usually results from a hole in the retina that allows the
vitreous humor to leak between the choroid and the retina. Severe trauma to
the eye, such as a contusion or penetrating wound, may be the proximate
cause, but in the great majority of cases retinal detachment is the result of
internal changes in the vitreous chamber associated with aging, or, less
frequently, with inflammation of the interior of the eye.
