title: Isolated complete bitemporal hemianopia in traumatic chiasmal syndrome.
abstract: A 29-year-old man presented with a chief complaint of lateral blindness in the left eye at 4 months after an accidental fall. His best corrected visual acuity was 0.7 in the left eye and 1.0 in the right eye. Visual field test showed a complete bitemporal hemianopic defect without any neurologic symptoms. An orbital computed tomography scan with non-enhancement conducted at the time of the visit showed multiple frontal skull fractures and cerebromalacia a small fracture in the sphenoidal boneboth frontal lobes. No radiological abnormalities of the visual pathway were detected. Optical coherence showed reduced thickness in the retinal nerve fiber layer, primarily in the superior and inferior part of the left eye. To our knowledge, a complete bitemporal hemianopia without neurological deficits is extremely rare in traumatic chiasmal syndrome.
