Choroidal detachment is caused by the accumulation of fluid or blood in the potential suprachoroidal space. Hemorrhagic choroidal detachment is due to rupture of the choroidal vessels and may occur following intraocular surgery, penetrating ocular trauma or contusion, or spontaneously (rare). On CT, it appears as a mound-like area of high density, which may be quite large and irregular. The detached leaves of the choroid are separated posteriorly and assume a U-shape with the intervening posterior wall of the globe. In more advanced stages, the detached leaves may become more convex, yielding the "kissing choroid" sign. Hemorrhagic choroidal detachment significantly affects the prognosis of the injured eye and very often warrants surgical intervention.
