Posterior ocular staphyloma

Imaging studies show thinning of the sclera with focal bulge.

May be unilateral or bilateral.

Computed tomography (CT) shows bulging of posterior aspect of the globe away from optic disc, usually on the temporal aspect.

Scleral thinning is associated with focal bulge.

May see associated retinal or choroidal detachment, with or without hemorrhage.

Magnetic resonance imaging (MRI) shows bulging of the posterior aspect of the globe away from the optic disc, usually on the temporal aspect.

Scleral thinning is associated with focal bulge.

May see associated retinal or choroidal detachment with or without hemorrhage.

Ultrasound (US) can well demonstrate and follow posterior staphylomas.

US can demonstrate and follow associated choroidal and retinal detachments.

US can readily exclude associated intraocular tumors.

Many posterior staphylomas first come to the attention of the radiologist as incidental imaging findings on CT and MRI studies.
