Silicone implants for treatment of retinal detachment: computed tomographic appearance.

The use of silicone rubber implants for repair of retinal detachments has become a common mode of therapy in recent years. Medical-grade silicone rubber is nonallergenic, easily cut to an appropriate size with scissors, and does not support bacterial growth. Several patients with these implants were studied recently by computed tomography. The characteristic computed tomographic appearances of these implants are discussed.
