Hutchinson's patch (or salmon patch of Hutchinson ) is a dull orangish-pink area (generally without clear boundaries) on the cornea , most often found at the periphery of the cornea. The sign is an indication of interstitial (or parenchymatous) keratitis , causing corneal neovascularisation .[ 1] [ 2] [ 3]
Blood vessels derived from the ciliary vessels are thickly set in the layers of the cornea and produce a dull red color—"the salmon patch of Hutchinson." These patches may be small and crescent-shaped, or large and sector-like.[ 4]
It is named after the English physician Jonathan Hutchinson (1828–1913).[citation needed ]
