摘要： The basic principle in repairing retinal detachments is closing the retinal break. An internal tamponade is a material suitable for intraocular use which is used to directly close a retinal break. A scleral buckle is a flexible device which can conform to and allow movement of the sclera. A new method to treat retinal detachment is to combine usage of a magnetic fluid tamponade with a magnetized flexible scleral buckle, which effects tamponade of the retina without interfering with vision. A substantial percentage of complicated retinal detachments currently go on to blindness despite multiple attempts at surgical intervention because of our inability to tamponade retinal breaks in certain locations. In a cross-sectional view of the eye, the retina and choroids sit on the sclera. Each break in the retina therefore sits on a specific location on the sclera. The magnetic scleral buckle (msb) is positioned on the exterior aspect of the sclera at the location of the retinal break, employing the msb's trans-scleral magnetic field, and magnetically attracts the silicone magnetic fluid to the retinal break. This system of silicone magnetic fluid and magnetized scleral buckle can thus tamponade retinal breaks wherever they occur.
