Choroidal detachment MRI

Choroidal detachment is accumulation of blood or fluid in supra choroidal space between choroid and sclera, so collection extend circumferentially along the entire supra choroidal space, configuration is lentiform shaped along medial as well as lateral wall of globe, choroid bulging medially on either side giving so called kissing choroid sign. Anteriorly extend upto ciliary bodies and posterior limit formed by anchoring effect of short posterior ciliary arteries and nerves preventing convergence of detached choroidal leaves to a single point.

MRI can accurately differentiate between choroidal and retinal detachment depending up on configuration of the collection.
