    Author: Lowitzsch K, Welkoborsky HJ.
    Journal: EEG EMG Z Elektroenzephalogr Elektromyogr Verwandte Geb; 1987 Dec; 18(4):179-84. PubMed ID: 3123195.
    Abstract:
    The pattern-reversal VEP with different check size and the computerized perimetry in the 10 degrees and 30 degrees radius field were recorded in 22 patients suffering from unilateral optic neuritis diagnosed by historical as well as by clinical findings. During the acute attack 12/22 optic neuritis eyes and 3/22 partner eyes had a diminished visual acuity below 0.7. After the attack the visual acuity remained reduced in 9/22 of the affected and 2/22 of the nonaffected partner eyes. The VEP was prolonged in 19/22 optic neuritis eyes and in 12/22 partner eyes applying 50' checks and in 15/22 resp. applying 15' checks. The computed visual fields showed depressions in 21/22 optic neuritis-eyes and in 15/22 partner eyes within in the 30 degrees radius field. VEP and computerized perimetry, there for, can detect subclinical affections of partner eyes in unilateral optic neuritis in a very high percentage.
