Learning objectives Describe the radiological presentation of post-surgical changes in glaucoma, cataracts, and retinal detachment. Exhibit the characteristics that differentiate implanted surgical devices from foreign bodies and other mimics.
Read more Background There is a wide range of ophthalmologic procedures and interventions involving the orbital content, such as surgical treatment of glaucoma, cataracts, retinal detachments, ocular traumas, and neoplastic lesions. These are often visible and easily characterized in imaging studies conducted for other causes. Recognizing the various manifestations of these post-surgical changes is crucial to avoid misinterpretations. Additionally, several types of implanted devices can be identified using imaging techniques, such as glaucoma drainage devices, orbital implants, and eyelid weights.
Read more Findings and procedure details Glaucoma ranks as the third most common cause of irreversible blindness in adults. Surgical treatment options for glaucoma include trabeculectomy and the use of devices such as EX-PRESS or the Glaucoma Drainage Device, with the latter often being mistaken for foreign bodies. Cataracts are the most common cause of reversible blindness in adults. The most frequently used surgery is phacoemulsification, whose post-surgical changes are easily detectable in both CT and MRI scans. Surgical treatment for retinal detachment includes scleral buckles and vitrectomies,...
Read more Conclusion There is a wide range of ophthalmologic surgical interventions, and recognizing post-surgical manifestations on imaging is crucial to avoid misdiagnoses.
