| Summary: |
Purpose: The aim of
the study was to analyze the cases of retrobulbar
neuritis and their connection with multiple sclerosis.
Material and methods: We follow in a
retrospective (1989-2004) study 86 patients with
retrobulbar optic neuritis, 59.3% of whom were females
and 40.7% males.
Results: Recurrent retrobulbar optic neuritis was
observed in 8 patients (9.3%), it was 7% of all eyes and
in 27 patients (31.4%), that is 47.8% of all eyes, it
was bilateral. Multiple sclerosis was diagnosed in 8
cases, the same number of the patients was already
treated because of SM. The most common initial symptom
was decrease in visual acuity, which was poor (0.1 or
worse) in 60% of the cases at the beginning. Pain
occurred in 29.7%, pupillary defects in 28.7%, temporal
or total pallor of the optic disc in 32.6% of the
patients. Central field defect was rather rare in the
group studied (22.7%), to compare with paracentral or
peripheral one (46.6%). In most cases of the visual
evoked potentials we noticed the elongation in the
latency of P100. Among 31 cases of MRI examination of
the central nervous system demyelination lesions have
been revealed in 25.8% .
Conclusions: We observed more cases of bilateral
optic neuritis and paracentral defects than other
authors. A number of diagnosed multiple sclerosis
patients was high taking into consideration relatively
short period of observation. |
