[Visual evoked potentials in optochiasmal arachnoiditis].
Visual evoked potentials (EP) were studied in 24 patients with optochiasmal arachnoiditis. Distinct changes were registered in the visual EP in the form of increased latent period of the response, diminution of its amplitude and separability, and poor structuralization. The critical level of visual acuity for the specific and nonspecific visual EP was determined. From analysis of the visual EP time-course during treatment the authors established the criteria of the prognosis for the recovery of visual functions in patients with optochiasmal arachnoiditis.
