[Follow-up of retrobulbar neuritis with the octopus computer perimeter (author's transl)].

Methodological possibilities of quantifying the visual field course in retrobulbar neuritis were studied. In nine patients suffering from this condition the visual field had been examined repeatedly using the Octopus computer perimeter (program 31, stimulus size 3). Total loss of sensitivity and the number of test points with pathologic results had been chosen to correlate to recovery of visual function. These parameters, as well as visual acuity, were compared with the cumulative steroid dose. It is concluded that rapid recovery of visual function with initial steroid therapy may have a starter effect for spontaneous further improvement of sensitivity in the central visual field. However, a prospective, controlled clinical trial would be required to provide definite proof of the usefulness of steroid therapy in retrobulbar neuritis.
