Clinical Signs:
Edema, congestion, cyanosis (comb, wattle, eyelids)
Morphologic diagnosis:
Eyelids: Diffuse edema. Comb: Diffuse edema, congestion and cyanosis. Wattle: Acute diffuse hemorrhage.
Clinical description:
This image was taken 2 days post experimental inoculation with highly pathogenic avian influenza. As seen here, subcutaneous edema of the periocular region often prevents the lids from fully opening, giving the eyes an “almond-shaped” appearance.
Pathologic description:
The eyelids of this bird are swollen and unable to fully open. The wattles and comb are slightly swollen and discolored red to purple. The wattle is particularly reddened.
