Sažetak
The curve of visual evoked potentials was observed and compared with changes of visual
acuity and visual field during a 24-month period in a group of 39 patients with optic
nerve injury as a result of mild cerebral trauma. Results of the study showed great
improvement of visual acuity and visual field after treatment, and slower and continuous
improvement of visual evoked potentials. The main abnormality of visual evoked
potentials is the shortening of amplitude, which is recorded to gradually recede after
treatment in half of the patients. Authors conclude that the shortening of amplitude can
be partially explained by the edema and the compression of fibers in the optic canal.
Also, they emphasize that in this type of optic nerve injury visual acuity testing is the
best indicator of the promptness and scope of the injury, while visual field research presents
the best method for following later delicate changes of visual function.
