Source-derived summary

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 in the superior temporal field of the optic nerve opposite the site of injury.

Editorial summary

The public source identifies “Wilbrand's knee” as anatomical landmark of the optic nerve. This brief keeps that definition visible, then builds a research path around Wilbrand's, knee and Anatomical.

Editorial reviewA dependable orientation record for establishing vocabulary, names and a first evidence trail. The current 46-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with Wilbrand's, knee and Anatomical providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Wilbrand's knee”, the useful work is to connect “anatomical landmark of the optic nerve” to the records capable of establishing context and consequence.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Oct 6, 2025. The linked authority identifier is Q25099310. None of the 0 selected statements returned an explicit reference.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
