[The retinal nerve fiber layer in retrobulbar neuritis].

In the course of 1 year we investigated 32 patients suffering from retrobulbar neuritis, using photographs of the retinal nerve fiber layer (RNFL). All photographs revealed defects of the RNFL in the area of the papillomacular bundle. These observations were compared with photographs of eyes not affected by any ophthalmological diseases. No loss of retinal nerve fiber bundles was found in any of these cases. One remarkable finding of this study was that 90% of the patients with retrobulbar neuritis also had defects in the RNFL of the contralateral eye.
