Silicone oil (SiO) and fluorosilicone oil (FSiO) are useful in difficult cases of retinal detachment surgery. Unidentified low-molecular-weight components (LMWC) and residual catalysts in SiO and FSiO have been implicated in the adverse reactions of the oils in the eye.

A gas-liquid chromatographic method was developed for the simultaneous assay of six local anesthetics, including amethocaine, bupivacaine, etidocaine, lignocaine, mepivacaine and prilocaine, in biological samples. These drugs and internal standard (clomipramine) in basified samples were extracted into 5 ml n-hexane
