Abstract
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 tamp…
