Postsurgical imaging of the globe.

Interpretation of globe imaging after ophthalmologic surgical intervention, just like postoperative imaging in any location, can create a diagnostic dilemma if the radiologist is not familiar with the type of surgery performed and the nature and location of any implanted devices. Certain implants and devices may create artifacts on computed tomography or magnetic resonance imaging, and some contain ferromagnetic components that may be damaged if inadvertently placed in the magnetic resonance imaging. We review several common ocular surgical procedures, as well as a few orbital surgical procedures and discuss many implants and devices and their appearance on cross-sectional imaging. Familiarity with these procedures and their imaging appearance can diminish the chance of misinterpretation.
