VISUAL EVOKED POTENTIAL CHANGES AND CLINICAL CHARACTERISTICS OF TILTED DISC SYNDROME
This study is planned to determine the clinical characteristics, visual field defects and visual evoked potential
(VEP) changes in tilted disc syndrome. 33 eyes of 20 patients with tilted disc sydrome was evaluated for refraction,
Goldmann visual field test and visual evoked potentials.
Visual field defects were detected in 27 (81.1%) eyes. The most common visual field defect was superior
temporal quadranopsia in 11 (33.3%) cases. Additionally, enlargement in the blind spot was detected in 8 (24.2%),
concentric narrowing in 5 (15.2%) superior altitudinal defect in 4 (12.1%) and paracentral scotoma in 4 (%12.1%)
patients.
Increased latency in P 100 wave was detected In 27 of 33 tilted disc cases. 22 of these 27 patients have
increased latency time with pattern diffuse VEP and VEP abnormalitis were detected in 4 patients with no visual field
defects.
This data shows that although VEP changes support the diagnosis of tilted disc syndrome it has limited value in
differential diagnosis. It is important to know the clinical characteristics of tilted isc syndrome for differential diagnosis
and to avoid unnecessary neuro-radiologic imaging.Keywords: Tilted disc syndrome, Visual fields, Visual evoked potentials, Chiazmal syndrome
