Silicone oil endotamponades need to be injected and removed in a reasonable time and under moderate pressure conditions. However, due to ever-decreasing sizes of incisions and trocars, injection and removal of highly viscous silicone oils is very time-consuming. To address resulting problems like longer treatment times or hypotony, thixotropic silicone oils were developed. These oils are characterized by a diminished viscosity under constant mechanical stress; whilst there is pressure or vacuum acting on it, the oils will become more fluid and, therefore, much easier to be applied. Once the force is being removed from the oil, it will automatically return to its initial viscosity after a short time.
