[Importance of correct interpretation of incidental detection of intraocular administration of silicone oil on the CT image].
Liquid silicone is used in ophthalmology as one of the possible substitutes of the vitreous body and for internal tamponade of the vitreous space in pars plana vitrectomy (PPV). The intraocular presence of silicone causes marked changes of the CT image of the bulbus. As the number of patients treated by PPV is steadily increasing (this applies in particular to patients with diabetes and AIDS), the probability increases that the radiologist will encounter this image. Typical changes in the CT image of the bulbus after PPV using a silicone cerclage strip with administration of silicone oil (SO) into the vitreous space: 1. Disfiguration of the bulbus after application of the cerclage strip, 2. the area of the vitreous body is visualized as a hyperdense area with a slit-like hypodense space between SO and the bulbar wall. Knowledge of these changes will avoid errors in the interpretation of accidentally recorded CT images.
