Psychophysical assessment of a patient with Tolosa-Hunt syndrome.

Abstract

Patients may complain of impaired vision and yet exhibit no abnormalities when tested with conventional tests of visual acuity. Some sensitive psychophysical tests used by psychologists and neurophysiologists to examine the function of the normal visual system are beginning to gain recognition as useful tools in clinical situations. They are particularly sensitive indicators of damage to the visual pathways. The results are presented of one such application which characterises the visual defects of a patient with a suspected diagnosis of Tolosa-Hunt Syndrome.
