摘要
PURPOSE: To demonstrate the clinical-radiologic correlation between a junctional scotoma and a focal lesion compressing the prechiasmatic segment of the distal optic nerve. METHODS: Case report involving a man with a pituitary adenoma. Clinical correlation was determined by reviewing visual field evaluations and magnetic resonance images, RESULTS: The tumor compressed the prechiasmatic segment of the distal optic nerve bur not the optic chiasm, producing a junctional scotoma documented by Goldmann and automated perimetry, The visual field defect resolved after neurosurgical decompression of the anterior visual pathway, CONCLUSIONS: A junctional scotoma can be caused by focal as well as large and diffuse lesions injuring the anterior visual pathway, specifically at: the junction of the optic nerve and chiasm, This finding supports the existence of Wilbrand fibers.
