Purpose:
To describe the role of multiplanar reconstruction and three-dimensional volume-rendered imaging in the assessment of silicon-based scleral buckle (SB)-related complications.
Methods:
Five eyes of five patients with SB-related complications where the history, surgical notes, and clinical examination proved inconclusive were included. Unenhanced axial orbital computed tomography images of all patients were acquired parallel to orbitomeatal line, and images were reviewed in orthogonal planes. The volume rendition of the imaged volume was evaluated in various tilts, with special reference to the spatial relationship of the band-buckle to the globe and bony orbit. All patients underwent imaging-assisted SB removal.
Results:
Imaging assisted in in vivo localization of the obscure band or buckle in all five eyes. Band was seen as hyperdense structure encircling whole of the globe, whereas buckle was seen as segmental, broad, hyperdense structure with scleral indentation. Presence of SB was identified in three patients, and globe integrity was shown in the other two. Abnormal anterior displacement of band and buckle was demonstrated in three cases on volume-rendered imaging in relation to lateral orbital rim. Focal exuberant soft-tissue proliferation around the buckle was present in all patients, suggesting chronic inflammation and infection. Successful removal of band and buckle could be achieved, and all patients were relieved of their preoperative complaints. No complication occurred during intraoperative and postoperative period.
Conclusion:
Use of multiplanar reconstruction and three-dimensional volume-rendered computed tomography imaging played a pivotal role in surgical success.
