Presentation
Headaches. Had surgery of the left eye 18 years ago.
Patient Data
Left retinal detachment with a typical V-shape and posterior insertion into the optic disc. The subretinal space fluid is of intermediate signal on T1 and high signal on T2 and FLAIR (chronic hemorrhage).
Hyperdense ring encircling the left ocular globe (previous history of scleral buckle surgery).
Normal appearance of the right ocular globe.
Mild cerebral volume loss with mild chronic small vessel ischemic change.
Case Discussion
CT features of scleral buckle surgery for retinal detachment 18 years prior.
Scleral buckles are devices (often made from silicon) implanted into the eye for the treatment of retinal detachment. They are performed to relieve vitreous traction which closes the defects in the retina and reduces the recurrent detachment. They are usually permanent and removed only if there is a complication such as a device infection or extrusion.
