Internal tamponade potency

Internal tamponade potency is the capacity to obdurate a dehiscence. It is correlated to the surface pressure of the product used. Schematically, the higher the tension, the stronger the tendency of the fluid to form a single bubble and to remain in the vitreous cavity without running through retinal dehiscences into the subretinal space. As a result, no fluid is passing through retinal dehiscences, which makes retinal reapplication possible. The internal tamponade potency is unrelated to the viscosity of the product.
