Crow's feet sign Superficial partial-thickness facial burns displaying the unburned crow's feet (魚尾紋) around the eyes. The presence of crow's feet sign correlates well with the absence of ocular injury. Sudden exposure to heat (e.g., hot water, steam, and flames) can activate the menace response. This reflex blinking occurs in response to the optical stimulus of a rapidly approaching object or perceived threat. This rapid eye closure results in the crow’s feet sign, represented by lateral lines of skin at the canthi that are spared from thermal damage. The presence of crow’s feet sign has been found to have a negative predictive value for an ocular injury and, in the context of forensic medicine, is indicative of consciousness at the time of injury.
