Evaluation of eyes harbouring perfluorocarbon liquid with standardized ophthalmic echography

For the detection of perfluorocarbon liquid (PFCL) left in the globe after vitreoretinal surgery, the method of standardized ophthalmic echography proved to be very helpful and effective. Larger amounts as well as only a few remnant drops of PFCL are represented in standardized A-scans and in contact B-scans by typical acoustic signals caused mainly by the slow velocity of ultrasound in PFCL. A safe differentiation from other intraocular conditions can be made with standardized echography.
