[Informativeness of different methods of visual stimulation in optochiasmatic arachnoiditis].

A comparative assessment of the informative value of visual evoked potentials (VEPs) has demonstrated that registration of VEPs in response to a diffuse flash of light makes it possible to objectively evaluate the status of the visual analyzer and to trace the course of the development and regression of the pathological process. In a long-term period of the recovery of the visual function in order to elucidate fine mechanisms of visual perception and to achieve objective optical correction of visual acuity, it is advisable to use VEPs in response to a structural stimulus.

[Testing of visual function by the evoked potential method before and after surgical treatment of optico-chiasmal arachnoiditis].

Dynamics of changes of visual evoked potentials recorded in patients with optico-chiasmatic arachnoiditis in response to a flash of light were revealed during restoration of visual function in the postoperative period. In improvement of visual functions no changes were found of evoked potentials recorded in a chess pattern in the immediate postoperative period.
