====== Wilbrand's knee ======

Inferonasal fibres of the [[optic nerve]] which go into the contralateral optic nerve 4 mm before crossing over to the opposite [[optic tract]]. A lesion here produces a [[junctional scotoma]].

Compression of the [[optic nerve]] near the [[chiasm]] may produce a superior temporal quadrant defect in the contralateral [[eye]] ([[junctional scotoma]] "pie in the sky" defect) from injury to the anterior [[Wilbrand's knee]]
