Use of electroacoustic localisation in the management of intraocular foreign bodies.

A new model of the electroacoustic discriminator and localiser has been put into production, and this paper reports on the preproduction model during its trial period in the management of patients with intraocular foreign bodies. Its particular advantage in localisation at the time of surgery and the procedure for using it are described. The visual results following surgical extraction of 17 cases of magnetic foreign bodies in the posterior segment are outlined.
