摘要：

Retinal detachment is repaired by external and internal tamponade. There is as yet no direct internal tamponade which provides 360 degrees coverage to the retina. With a magnetized encircling scleral buckle, magnetic fluids would provide 360 degrees encircling internal tamponade. Our magnetic fluid is a dispersion of ultrafine- (4-10 nm) magnetic particles in silicone secured with triblock copolymer steric stabilizers. Triblock copolymers are good steric stabilizers for suspensions of gamma-Fe2O3 powder in octamethylcyclotetrasiloxane (D-4). (C) 1999 Elsevier Science B.V. All rights reserved.
