[Tensilon tonography in the diagnosis of myasthenia gravis].

The concomitant intravenous administration of Tensilon during tonography was performed on a group of 15 myasthenic patients and ten "control" subjects, including patients with oculoparesis of known cause other than myasthenia. The myasthenic group uniformly responded with increases of intraocular pressure. There was no instance of this response in nonmyasthenic subjects when challenged with Tensilon. It is suggested that "Tensilon tonography" is a diagnostic procedure of greater sensitivity than the standard Tensilon test for myasthenia gravis with ocular involvement.
