Choroidal rupture involves rupture of which ocular layer?

Choroidal rupture involves rupture of which ocular layer?

• A. Choroid
• B. Retina
• C. Sclera
• D. Cornea

Answer: (A)

Choroidal rupture is a tear through the choroid, the vascular layer lying between the retina and the sclera. Blunt trauma places shear stress on the posterior eye, causing a crescent-shaped rupture in the choroid that often involves Bruch’s membrane as well. The retina overlying the rupture can be damaged secondarily, and subretinal or choroidal hemorrhages may accompany it, but the primary site of disruption is the choroid. The sclera lies behind and around this layer, and the cornea is the anterior surface—these are not the primary structures involved in a choroidal rupture.
