DEF

The constriction of a retinal vein at artery-vein-crossing.

CONT

AV nicking: The most commonly accepted belief is that the crossing phenomenon was due to venous compression by a thickened arteriole within the shared sheath (the Gunn sign). Impeded circulation results in a dilated or swollen vein peripheral to the crossing, causing hourglass constrictions on both sides of the crossing and aneurysmal-like swellings.

OBS

arteriovenous nicking: term recommended by the Medical Signs and Symptoms Committee.
